The carbon source separation from fermented sewage sludge for stimulation of denitrification and bisphenol A removal

Since biodegradable carbon source was helpful for both denitrification and cometabolic biodegradation of synthetic organic compounds, the study attempted to obtain a novel liquid carbon source from alkaline hydrolysates of co-fermented sludge and food wastes (HFSF) for the stimulation of denitrification and bisphenol A (BPA) removal in the biofilm system. The biofilm with function of denitrification was cultivated from sequencing batch biofilm reactor, having abundant denitrifiers (Acinetobacter, Paracoccus, Comamonas, Hyphomicrobium, Flavobacterium, etc.). Appropriate addition of HFSF in the systems with mature biofilm could significantly enhance denitrification and BPA removal, while no positive relation occurred. Optimum performances (with denitrification rate of 1.68 mg (Lh)−1, PDN of 0.348 g N g−1 COD, BPA removal rates of 87.8 ± 4.5%, and less than 100 mg L−1 COD) were obtained at COD/N ratio of 6.0. Optimum HRT was 12 h to avoid nitrite and ammonium accumulation. Biofilm EPS increased as influent COD/N ratio raise from 2.0 to 6.0, which might be related with BPA removal.

Photocatalytic degradation of bisphenol-A under UV-LED, blacklight and solar irradiation

This study aims at investigating the photocatalytic treatment of bisphenol-A (BPA) under various irradiation sources in order to identify cleaner and more sustainable technologies compared to conventional photocatalytic wastewater treatment systems. For this purpose, parallel experimental runs were carried out in two batch-operated slurry photoreactors under UVA irradiation provided by either a light-emitting diode (UV-LED) or a UV blacklight lamp (UV-BL), as well as in a solar compound parabolic collector (CPC) reactor under natural sunlight. The effect of key operating parameters, such as the initial BPA and TiO2 concentrations, water matrix, and treatment time, on the efficiency of the three photocatalytic systems was evaluated. The photocatalytic degradation of BPA was found to fit well with the pseudo-first-order kinetic model. BPA removal rate increased with catalyst concentration and with decreasing the initial concentration of BPA. The addition of humic acids was found to be inhibitory for all photocatalytic systems. At the best conditions assayed (C0 = 2.5 mg/L, TiO2 = 250 mg/L), BPA was completely degraded within 20, 30, and 120 min under UV-LED, solar, and UV-BL irradiation, respectively. The corresponding reaction rates were 0.230, 0.151, and 0.025 min−1, and TOC removal was 88, 67, and 33% after 90 min of treatment. In all cases, TiO2/UV-LED achieved the highest removal efficiency and it was found to be significantly more energy-efficient than the TiO2/UV-BL system. All in all, LED-driven photocatalysis was found to be advantageous over conventional TiO2/UV-BL systems in terms of performance and sustainability, and an appropriate alternative to solar photocatalysis in areas where sunlight is inadequate.

Synthesis of reusable multifunctional electrode for high performance supercapacitors and efficient bisphenol A degradation

In this research, we report a reusable multifunctional electrode, which can not only be used for supercapacitors, but can also act as the anode material for the degradation of bisphenol A (BPA) by the advanced electrochemical oxidization technology. This multifunctional electrode was prepared by growing MnO2 nanoflakes directly on a Ni foam substrate using a facile hydrothermal method. When substituted for the electrode in a supercapacitors, the specific capacitance was 846.1F/g at 5 mV/s. Furthermore, when used as anode material for degradation BPA in the advanced electrochemical oxidization process. The BPA removal rate is 99.7%, and this rate can be maintained at about 85.6% after 5 cycles. It is hoped that this electrode will provide new opportunities for the cooperation of energy and the environment in the future.

High efficiency and rapid degradation of bisphenol A by the synergy between adsorption and oxidization on the MnO2@nano hollow carbon sphere.

In this research, a novel efficiency MnO2@Nano hollow carbon sphere (MnO2@NHCS) nanocomposite was prepared by one-pot hydrothermal reaction with KMnO4 solution. The adsorption and oxidization performance of MnO2@NHCS were assessed by degradation of bisphenol A (BPA) at different conditions. The effect of dosage of MnO2@NHCS, pH, initial concentration of BPA, temperature and humic acid were investigated systematically. Moreover, the characterizations of MnO2@NHCS were measured by a series of techniques, such as XRD, FESEM, HRTEM, TGA and XPS. Notably, hollow structure of nano carbon sphere was still retained with uniform MnO2 nanosheets covered. The results show that the removal rate of BPA was 95.3% within 10 min and BPA can be almost decomposed in 30 min under the optimal conditions. Additionally, the MnO2@NHCS remained stable and had a high regeneration efficiency (more than 85%) after 3 cycles (360 min). The reaction intermediates/products of oxidation of BPA were analyzed and the possible degradation pathways of BPA were proposed. These research results demonstrate that the MnO2@NHCS is a fleet and efficient material for BPA degradation in aqueous environment.

Removal of Bisphenol-A from Aqueous Solutions by Pseudomonas aeruginosa in Batch Reactors: Effect of Carbon Source, Temperature and Concentrations

AbstractThis study was carried out to investigate the potential ofPseudomonas aeruginosafor the removal of bisphenol-A (BPA) from synthetic wastewater. To achieve this, BPA removal capability ofP. aeruginosawith respect to BPA concentration, and temperature were examined in batch reactors. Experiments were conducted in the presence/absence of glucose, as a carbon source. The first set of experiments consisted of evaluating the kinetic of removal of BPA at different concentrations (5, 10, 20, and 30 mg BPA/L) without glucose. In the second set of experiments, three different glucose concentrations (0.5, 1.0, and 2.0 glucose/L) with BPA concentrations were tested. After settlement of theP. aeruginosabiomass in the shakers, supernatants and control groups were filtered and analyzed for BPA using high performance liquid chromatography. In the biotic study, BPA removal rates were between 63 % and 100 %. All concentrations of BPA under 20 mg/L were completely degraded at 25 and 35 ºC at first step. However, 30 mgBPA/L was decreased to 8.56 mg/L byP. aeruginosaat first step at 25 ºC. At the second step, all concentrations of BPA were completely degraded by the cells at the presence of glucose. Hence, it can be summarized that bisphenol A can be used byP. aeruginosaas an external carbon source in the wastewater environments.

Degradation of bisphenol A and acute toxicity reduction by different thermo-tolerant ascomycete strains isolated from arid soils

Four different laccase-producing strains were isolated from arid soils and used for bisphenol A (BPA) degradation. These strains were identified as Chaetomium strumarium G5I, Thielavia arenaria CH9, Thielavia arenaria HJ22 and Thielavia arenaria SM1(III) by internal transcribed spacer 5.8 S rDNA analysis. Residual BPA was evaluated by HPLC analysis during 48 h of incubation. A complete removal of BPA was observed by the whole cell fungal cultures within different times, depending on each strain. C. strumarium G5I was the most efficient degrader, showing 100% of removal within 8 h of incubation. The degradation of BPA was accompanied by the production of laccase and dye decolorizing peroxidase (DyP) under degradation conditions. The presence of aminobenzotriazole (ABT) as an inhibitor of cytochrome P450s monooxygenases (CYP) demonstrated a slight decrease in BPA removal rate, suggesting the effective contribution of CYP in the conversion. The great involvement of laccase in BPA transformation together with cell-associated enzymes, such as CYP, was supported by the identification of hydroxylated metabolites by ultra-high performance liquid chromatography-mass spectroscopy (UHPLC-MS). The metabolic pathway of BPA transformation was proposed based on the detected metabolites. The acute toxicity of BPA and its products was investigated and showed a significant reduction, except for T. arenaria SM1(III) that did not caused reduction of toxicity (IC50 < 8%), possibly due to the presence of toxic metabolites. The results of the present study point out the potential application of the isolated ascomycetes in pollutant removal processes, especially C. strumarium G5I as an efficient degrader of BPA.

The combination of Fenton process and Phanerochaete chrysosporium for the removal of bisphenol A in river sediments: Mechanism related to extracellular enzyme, organic acid and iron

In this study, Fenton process combined with bioremediation technology, as a novel treatment technology, was applied for the removal of bisphenol A (BPA) from river sediments. The removal rate of BPA reached 58.23% after 24 days of combined treatment, which was higher than those in the treatment with Phanerochaete chrysosporium (P. chrysosporium) alone (21.59%) or the Fenton treatment alone (14.48%). The degradation mechanism of BPA in treatment process was investigated. According to the analyses of pH, iron, enzyme activities and organic acids, it was found that there was a synergetic effect between Fenton process and P. chrysosporium treatment. The organic acids generated by P. chrysosporium created a better acid environment for Fenton reaction, and the ferrous iron introduced by Fenton reagents might stimulate the development of P. chrysosporium. In addition, β-cyclodextrin (β-CD) is a good chelating agent together with excellent bioavailability, so we investigated the influence of β-CD on the combination treatment. Results showed that β-CD was able to promote the combination treatment. We also obtained that the optimal dosage of FeSO4 (270 mmol/L), ratio of Fe2+ to H2O2 and dosage of β-CD (13 mmol/L) were 0.5 mL, 1:14 (mol/mol), 1 mL, respectively. The combined treatment under mild reaction conditions provides a new way for the removal of BPA from polluted river sediments.

Stability of BiFeO3 nanoparticles via microwave-assisted hydrothermal synthesis in Fenton-like process.

Stable catalysts require high catalytic efficiency and repeated consecutive use, low mass loss, and metal leaching. This study investigated BiFeO3 (BFO) composite with high stability and reusability using a one step microwave-assisted hydrothermal method (MAHS) to decompose bisphenol A (BPA) used as the target contaminant. After six consecutive reaction cycles in microwave-enhanced Fenton-like process (MW-Fenton-like), the removal rate of BPA decreased from 94 to 87.4% with low metal leaching ratio and mass loss. The morphology, crystal, reaction kinetics, and hydroxyl radical (·OH) were used to demonstrate the high stability of BFO-MAHS. The results indicated that the benign stability and reusability of BFO-MAHS probably occurred because (1) the thermal-effect of MW improved heating rate, which led to the rapid formation stable cube structure and (2) MW mechanical vibrations existed in the preparation process, which further enhanced the cube structure. Therefore, MAHS could be used as a green and environmental friendly method to apply in catalysts synthesis, which could immensely shorten preparation time and enhance the catalytic performance with no waste production.

Combination of photoelectrocatalysis and adsorption for removal of bisphenol A over TiO2-graphene hydrogel with 3D network structure

We successfully fabricated the three-dimensional (3D) hydrogel of titanium dioxide (TiO2)-graphene using a simple one-pot method and exhibited enriched adsorption-photoelectrocatalytic degradation ability of low-concentration bisphenol A (BPA). Combined with the unique adsorption of graphene hydrogel and the effective photoelectrocatalytic performance of TiO2, we rapidly enriched the organic pollutants and conducted efficient in situ degradation. The low-concentration BPA (20mg/L) was degraded completely by the TiO2-rGH electrode in 5h through the synergistic effect of adsorption-photoelectrocatalytic. The photogenerated charge on the surface of TiO2 is rapidly separated by the action of the applied electric field and the graphene sheet. The high conductivity of the graphene makes the TiO2-graphene hydrogel rapidly conducting the charge and solves the problem of poor conductivity of the semiconductor electrode. On the basis of these advantages, the TiO2-rGH has a cross-porous network structure that favors the anchor of more TiO2 nanocrystals, the specific surface area and reactive sites are greater than the thin film electrode, and the structure is conducive to significantly improving the BPA removal efficiency. By contrast, the BPA degradation of TiO2-rGO thin film electrode was 40% after 4h of ultraviolet irradiation, whereas the removal rate of BPA over the same mass of TiO2-rGH electrode rate was up to 96%. At the same time, the TiO2-rGH electrode without filtering can be achieved quickly separated from the recovery due to its special macro-3D network structure. Its removal ability still maintains above 90% after 10 times cyclic experiments with self-regeneration characteristics. It can be achieved rapid separation and recovery without filtering.

The experimental investigation of bisphenol A degradation by Fenton process with different types of cyclodextrins

In this work, the degradation efficiencies of bisphenol A (BPA) by Fenton reaction were compared systematically with varying cyclodextrins. The results showed that the removal rate of BPA displays a considerable increase by Fenton reaction in presence of β-cyclodextrin (β-CD) and its derivatives. Specifically, 98±2% and 89±2% of BPA was removed with carboxymethyl-β-cyclodextrin (CMCD) and β-CD, respectively. Additionally, to understand the reaction mechanism, the structure activity of cyclodextrins with substrate and the kinetic of Fenton reaction with cyclodextrins have been investigated. Results showed that the structure activity was the major role for cyclodextrins in this system.

Adsorption and degradation of 14C-bisphenol A in a soil trench

Bisphenol A (BPA) has caused widespread concern among scholars as a result of its estrogenic toxicity. It exists mainly in natural waters, sediments, and soil, as well as sewage and wastewater sludge. Considering that BPA is a common environmental pollutant that is removed along with chemical oxygen demand (COD), nitrogen, and phosphorus in drainage treatment systems, it is important to research the fate of BPA in sewage treatment systems. In this research, laboratory batch experiments on soil degradation and adsorption were conducted with 14C-BPA, aiming to discuss the transport and degradation characteristics of BPA in both simulated facilities and a soil trench. Based on the experimental results, the Freundlich model could be applied to fit the isothermal adsorption curve of the BPA in soil. A low mobility characteristic of BPA was discovered. The mineralization rate of BPA was fast and that of the reaction showed small fluctuations. After degradation, 21.3 and 17.7% of the BPA groups (the experimental group treated with ammonia oxidase (AMO) inhibitor and the control group) were converted into 14CO2, respectively. This indicates that the nitrification and degradation of BPA had a certain competitive relationship. Besides, nitrification did not significantly affect the soil residue of BPA. Through the soil trench test, the average removal rate of BPA in the soil trench was 85.5%. 14CO2 was discharged via the mineralization of BPA, accounting for 2.5% of the initial input. BPA easily accumulated in the bottom soil of the soil trench. BPA and its metabolites in the effluent accounted for 14.5% of the initial dosage. The residual extractable BPA and its metabolites in the soil accounted for 51.3%, and the remaining part of the unextractable residue represented 19.8% of the initial radioactive dosage.

Aquatic micro-pollutants removal with a biocatalytic membrane prepared by metal chelating affinity membrane chromatography

Biocatalytic membranes are promising to remove micro-pollutants in aqueous environment due to their mild and green operation condition. However, more efforts need to be devoted to improving their removal efficiency and stability. In this study, metal chelating affinity membrane chromatography (MCAMC) was used to construct a biocatalytic membrane by selectively capturing laccase from a crude fermentation broth. Metal ions had a significant effect on the activity of the immobilized laccase and copper ion was the best choice. A pH of 4.5 was selected for laccase adsorption and its loading seemed the same under flow rates from 0.5 to 10mLmin−1 thanks to the inherent convective transport of membrane chromatography. The pH value and salt concentration in the storage buffer had an obvious effect on the stability of the immobilized laccase, and the prepared biocatalytic membrane retained 87% of initial activity after 20days storage. When applying such membrane to micro-pollutant removal (taking bisphenol A (BPA) as an example), a high BPA removal efficiency (99.3%) could be obtained. The biocatalytic membranes could be operated at a high flux of 50Lm−2h−1 without recycling the permeate into the feed, and its throughput and BPA removal rate were superior to the most results in the literature. However, BPA removal decline (from 99.6% to 56.6% after five cycles) occurred during the successive water treatment due to the membrane fouling caused by BPA polymerization products. Membrane regeneration could be achieved by simple elution-cleaning-reloading, and the laccase activity and BPA removal were fully recovered.

Titanium dioxide-based sonophotocatalytic mineralization of bisphenol A and its intermediates.

In this study, bisphenol A (BPA) removal by sonophotocatalysis coupled with commercially available titanium dioxide (TiO2, P25) was assessed in batch tests using energy-based advanced oxidation combining ultrasound (US) and ultraviolet (UV). The kinetics of BPA removal were systematically evaluated by changing operational parameters, such as US frequency and power, mechanical stirring speed, and temperature, but also comparison of single and coupled systems under the optimum US conditions (35kHz, 50W, 300rpm stirring speed, and 20°C). The combination of US/UV/P25 exhibited the highest BPA removal rate (28.0×10-3min-1). In terms of the synergy index, the synergistic effect of sonophotocatalysis was found to be 2.2. This indicated that sonophotocatalysis has a considerably higher removal efficiency than sonocatalysis or photocatalysis. The removal of BPA was further investigated to identify BPA byproducts and intermediates using high-performance liquid chromatography-mass spectrometry. Five main intermediates were formed during sonophotocatalytic degradation, and complete removal of BPA and its intermediates was obtained after 3h of operation. The degradation pathway of BPA by sonophotocatalysis was also elucidated.

Aerobic granular sludge for bisphenol A (BPA) removal from wastewater

The potential of aerobic granules to treat BPA-rich wastewater and the morphology and species structure of the granules were investigated at influent BPA concentrations from 0 to 12 mg/L. The efficiency of BPA removal in sequencing reactors operated with 8-h cycles exceeded 97% and the BPA removal rate was highest (about 0.8 mg/(g MLVSS·h)) at 6 mg BPA/L. Ammonium removal started after BPA concentrations in the reactors dropped below 2 mg/L – after this, ammonium was fully removed in the reactor cycle at rates from 1.97 to 2.56 mg/(g MLVSS·h). Increasing BPA load diminished biomass production and extracellular polymers formation and increased granule diameters. As a result of the increased granule diameters, the core communities in the granules included not only aerobic genera such as Aquimonas and Pseudoxanthomonas, but also anoxic and anaerobic genera including Thauera and Azoarcus. Technological results and correlations between abundances of Methylobacillus sp., Nitrosospira sp. and Sphingomonas sp. and influent BPA concentrations indicated that BPA was both co-metabolized and directly biodegraded. Metabolic intermediates of BPA degradation were not present in the effluents. This study shows that aerobic granules effectively remove BPA and it extends knowledge of how BPA affects the morphology and microbial structure of aerobic granules.

Bisphenol A Removal by Submerged Macrophytes and the Contribution of Epiphytic Microorganisms to the Removal Process.

Bisphenol A (BPA), a typical endocrine disruptor, has been found in global aquatic environments, causing great concern. The capabilities of five common submerged macrophytes to remove BPA from water and the contributions of epiphytic microorganisms were investigated. Macrophytes removed 62%-100% of total BPA (5mg/L) over 12 days; much higher rates than that observed in the control (2%, F = 261.511, p = 0.000). Ceratophyllum demersum was the most efficient species. C. demersum samples from lakes with different water qualities showed no significant differences in BPA removal rates. Moreover, removal, inhibition or re-colonization of epiphytic microorganisms did not significantly change the BPA removal rates of C. demersum. Therefore, the contributions of epiphytic microorganisms to the BPA removal process were negligible. The rate of BPA accumulation in C. demersum was 0.1%, indicating that BPA was mainly biodegraded by the macrophyte. Hence, submerged macrophytes, rather than epiphytic microorganisms, substantially contribute to the biodegradation of BPA in water.

Performance of nitrogen-doped graphene aerogel particle electrodes for electro-catalytic oxidation of simulated Bisphenol A wastewaters

The treatment of effluent containing Bisphenol A (BPA) was investigated experimentally using nitrogen-doped graphene aerogel (NGAs) as particle electrodes in a three-dimensional electrode reactor for the electrochemical treatment was studied. The effects of the cell voltage, pH, the ratio of NGAs mass to solution volume and repeated times on the removal efficiency were investigated. Compared with commercial carbon particle electrodes, the NGAs exhibited stronger activity to remove BPA simulated wastewater. For 15mgL−1 of BPA solution, the degradation rate of BPA exceeded 90% after treatment for only 30min under the optimum conditions. The CODCr removal rate of BPA was 85%. Moreover, in the process of reused 50 times, the degradation rate of BPA can be kept in more than 85%. The CODCr removal rate was stable at about 73%. The intermediate products of electrochemical degradation of BPA were identified by liquid chromatography-mass spectrometry liquid chromatography (LC–MS), and a probable BPA degradation pathway was proposed. It was considered that OH radicals by water electrolysis could constantly attack the aromatic ring to form various intermediates such as hydroxylated-BPA, isopropylphenol, hydroquinone, phenol and butantetraol, maleic acid, oxalic acid. These compounds were eventually mineralized by electrolysis into CO2 and H2O.

Separation of bisphenol A and phenol from water by polymer adsorbents: Equilibrium and kinetics studies

The adsorption behaviours of some polymer adsorbents (Dowex Optipore L493, Diaion SP825 and Diaion SP 207) were evaluated for the removal of bisphenol A (BPA) and phenol from aqueous solutions. Dowex L493 exhibited higher adsorption affinity to BPA showing an adsorption capacity of 1.35mmol/g, while having less adsorption affinity to phenol with a capacity of 0.84mmol/g. The adsorption equilibrium data for BPA and phenol removal tested by Dowex Optipore L493, Diaion SP825, and Diaion SP207 were mainly fitted well to Freundlich isotherm model. According to the kinetic test results, both removal rates of BPA and phenol were obtained faster for Dowex L493 than Diaion SP825 and Diaion SP207. Results of kinetic study indicated that the adsorption kinetics were explained better by the pseudo-second-order kinetic model for BPA and phenol removal using all type adsorbents. Rate controlling step has been accepted as particle diffusion for almost all adsorbents. The capability of Dowex Optipore L493 to remove both BPA and phenol from aqueous solutions was found to be the highest among the adsorbents tested.

The Growth Behavior of Chlorella vulgaris in Bisphenol a under different Cultural Conditions

The effects of different initial concentrations of bisphenol A (BPA) on Chlorella vulgaris and removal capacity of BPA by Chlorella vulgaris were investigated under the light and the dark cultural conditions. Experiments were performed in 250 mL flasks under light and dark conditions with different BPA concentrations. Results showed that 0-20 mg·L-1 BPA concentration under the light condition and 0-10 mg·L-1 BPA concentration under dark condition plays a promoting role on the growth of Chlorella vulgaris in terms of cell density. The effect of BPA removal under light condition was obviously better than that under the dark condition. The maximum BPA removal rates were 3.425 ± 0.145 mg (L·d)-1 and 1.530 ± 0.025 mg (L·d)-1 under two conditions and were observed during 2-4 d and 0-2 d, respectively. The largest removal amounts of BPA under two conditions were all investigated in L-BPA50 and D-BPA50 groups. Both superoxide dismutase (SOD) and catalase (CAT) activities were promoted in all the treatments, which proved that C. vulgaris showed a positive response to the BPA stress condition. SOD activity showed sensitive and responsive to the new medium since it was promoted immediately on the incubation day. CAT activity was supposed to be more tightly controlled in response to BPA because its level was related to the BPA removal.

Optimization and Degradation Mechanism of Photocatalytic Removal of Bisphenol A Using Zn0.9 Fe0.1 S Synthesized by Microwave-assisted Method.

The sulfide photocatalyst of Zn0.9 Fe0.1 S was successfully synthesized by a facile microwave-assisted method, and Zn0.9 Fe0.1 S photocatalysts were characterized using SEM, EDX, XRD and BET. The specific surface area of synthesized Zn0.9 Fe0.1 S is 78.1 m2 g-1 , and total pore volume is 0.4 cm3 g-1 . With bisphenol A (BPA) as a target pollutant, photocatalytic system of UV + Zn0.9 Fe0.1 S + H2 O2 was set up. Some influencing parameters, including H2 O2 dosage, initial pH value, initial concentration of BPA and Zn0.9 Fe0.1 S dosage, were investigated, and the stability of the Zn0.9 Fe0.1 S was also studied during the photocatalysis. The optimum values of operating parameters were found at an initial pH value of 5.0, a H2 O2 dosage of 0.15 mmol L-1 and a Zn0.9 Fe0.1 S dosage of 0.08 g when the initial concentration of BPA was 10 mg L-1 . Under the optimal conditions, the highest removal rate of BPA achieved 95%. After seven consecutive reaction cycles, the degradation efficiency of BPA could still reach 85% and there was only a little dissolution of Zn2+ and Fe2+ . Compared with the traditional photo-Fenton system, the UV + Zn0.9 Fe0.1 S + H2 O2 system can not only improve the degradation efficiency of BPA, but also reduce the dosage of H2 O2 and thus reduce the processing cost.

Photodegradation of aqueous bisphenol A using boric acid-doped titanium dioxide

A high-photoactivity boric acid-doped titanium dioxide (B-doped TiO2) photocatalyst of the degradation of aqueous bisphenol A (BPA) under sunlight was synthesized and characterized by scanning electron microscope, X-ray photoelectron spectroscopy and UV-vis diffuse reflectance. The band gap energies of TiO2 and B-doped TiO2 (B/Ti mole ratio = 0.2%) were 3.01 and 2.98, showing that B-doped TiO2 could narrow the band gap of pure TiO2. In the photocatalytic kinetics of the photodegradation, the BPA photodegradation rate constants were 1.67 and 1.08 h−1, respectively. The BPA removal rate satisfies pseudo-first-order kinetics. Results showed that photocatalysts doped with boron displayed greater photodegradation (88% BPA removal) than pure TiO2 (65% BPA removal). Experimental results indicated that B-doped TiO2 not only was an effective photocatalyst, but also had considerable mineralization effects. The recycling test revealed that the photocatalyst remained effective after 10 uses, revealing the stability and reusability.
