Adsorption Of Naproxen Research Articles

Thermal, Chemical and ultrasonic assisted synthesis of carbonized Biochar and its application for reducing Naproxen: Batch and Fixed bed study and subsequent optimization with response surface methodology (RSM) and artificial neural network (ANN)

An adsorbent was synthesized using a cheap and locally available raw material, rice straw which was treated thermally and then chemically to form an activated rice straw biochar (ARSB). The ARSB was used for removing Naproxen, a widely used pharmaceutical compound. ARSB was used for the removing of Naproxen using both a batch and column study. The batch study was further optimised with using optimizing tools like artificial neural network (ANN) and response surface methodology (RSM). The isotherm, kinetics and thermodynamics of the adsorption process was analysed using the data of the batch study. A detailed analysis of the characteristics of ARSB was done by different characterization methods in order to acquire an in depth knowledge of its structural and functional characteristics. The highest removal was observed as 89.78% from batch study and 97.54% from Optimization study at pH 4, dose of 2.8 g/L using RSM. The adsorption of Naproxen on the ARSB was deduced to be following the Tempkin Isotherm and Pseudo second order kinetics. In case of the column study the highest efficiency was exhibited by the bed height of 7.62 cm and adsorbate concentration of 10 mg/L. The column study data was best explained by the Thomas model of column kinetics. From the regeneration study, it was found that the ARSB was able to maintain its effectivity even after repeated cycles of reuse.

Predicting adsorption behavior and anti-inflammatory activity of naproxen interacting with pure boron nitride and boron phosphide fullerene-like cages

The adsorption of naproxen (NPX) on surface of the boron phosphide (BP) and boron nitride (BN) fullerene-like cages have been studied and discussed by using density functional theory (DFT) and time-dependent density functional theory (TDDFT) calculations. Adsorption results using DFT demonstrated that B12N12 have strong interactions with the carbonyl (-C = O) group of naproxen via covalent bonding, while the interaction of the naproxen through a carbonyl and hydroxyl groups with the B12P12 occurred via electrostatic interactions, suggesting a large desorption time due to a large negative adsorption energy. The effects of hydroxyl (OH) functionalization on the adsorption of NPX via B12N12 has also been investigated. Results reveal that OH functionalization decreases the absolute Eb value of NPX on studied B12N12 fullerene-like cage. Theoretical studies also demonstrated the frequency shifts that is happening because of the adsorption process. The electronic and optical properties of B12N12 and OH-B12N12 in the presence of NPX are significantly sensitive. Interaction results demonstrated that B12N12 with H-donor functional groups such as –OH was effective for the delivery of naproxen as it leads to an increased dipole moment with weak binding energy. The polarity for the NPX loaded OH-B12N12 shows the feasibility of ameliorating the situation of solubility desirable for drug delivery systems in biological devices. Through the analysis of molecular docking, it was found that NPX loaded OH-B12N12 is potent inhibitors of TNF-α receptor and IL-1 receptor targets compared to B12N12 and B12P12 systems.

Equilibrium and kinetics studies of naproxen adsorption onto novel magnetic graphene oxide functionalized with hybrid glycidoxy-amino propyl silane

A hybrid silica-gel (3-glycidoxypropyl)trimethoxysilane/(3-aminopropyl)triethoxysilane magnetic graphene oxide (GPTMS/APTMS-MGO) nanocomposite was synthesized and used as an adsorbent for the magnetic removal of naproxen from water samples. The adsorbent was characterized using Fourier transform-infrared (FT-IR) spectroscopy, field emission-scanning electron microscopy (FE-SEM), energy-dispersive X-ray (EDX) spectroscopy, and transmission electron microscopy (TEM). The isotherm and kinetic studies showed that the data were fitted with Langmuir isotherm and pseudo-second-order kinetic models. The high adsorption capacity of 196 mg g−1 was obtained that indicated a monolayer sorption mechanism. The method was successfully applied for the removal of naproxen from wastewater samples and the removal efficiencies of 84–95% were obtained.

Removal of non-steroidal anti-inflammatory drugs from water by zeolite-rich composites: The interference of inorganic anions on the ibuprofen and naproxen adsorption

Composites of two natural zeolites – clinoptilolite and phillipsite, and cationic surfactants (cetylpyridinium chloride and Arquad® 2HT-75) were tested for the removal of two emerging contaminants – ibuprofen and naproxen. For each zeolite-rich rock, two different modifications of the zeolitic surfaces were prepared (monolayer and bilayer surfactant coverage). The influence of the initial drug concentrations and contact time on adsorption of these drugs was followed in buffer solution. The Langmuir model showed the highest adsorption capacity for the composite characterized by a bilayered surfactant at the clinoptilolite surface: 19.7 mg/g and 16.1 mg/g for ibuprofen and naproxen, respectively. Also, to simulate real systems, drug adsorption isotherms were conducted in natural water (Grindstone creek water – Columbia, Missouri, USA) by using the best performing adsorbent; in this case, a slight decrease of drug adsorption was recorded. Kinetic runs were performed in distilled water as well as in the presence of ions such as sulfates and bicarbonates; also, in this case, the interfering agents defined an adsorption decrease for bilayer composites.

Enhanced adsorption of naproxen from aquatic environments by β-cyclodextrin-immobilized reduced graphene oxide

In this study, a one-step hydrothermal method synthesized β-cyclodextrin-immobilized reduced graphene oxide composite (β-CD/rGO) was employed to remove naproxen from aquatic environments. The β-CD/rGO had a porous structure with abundant hydroxyl groups, and acetalization between the β-CD and rGO provided a more stable three-dimensional structure. The maximum equilibrium adsorption capacity of naproxen on β-CD/rGO at 313 K was 361.85 mg g−1. The adsorption of naproxen onto the β-CD/rGO fit well with the pseudo-second-order kinetics and the Langmuir adsorption model. The ΔH was higher than 40 kJ mol−1, which indicated that this adsorption was chemisorptive and endothermic. Host-guest interaction, hydrogen bonding, and π-π interactions were uncovered as three main mechanisms involved in binding between naproxen and the β-CD/rGO. Moreover, used β-CD/rGO could be regenerated with ethanol, making this an attractive method for naproxen adsorption in aquatic environments.

Application of a new choline-imidazole based deep eutectic solvents in hybrid magnetic molecularly imprinted polymer for efficient and selective removal of naproxen from aqueous samples

A magnetic molecularly imprinted polymer (Fe3O4@MIP) with naproxen (as template) was successfully prepared by adding a co-solvent consisting of a choline-imidazole based deep eutectic solvent (ChCl-BuIM) during polymerisation. The morphological, functional group, and magnetic characteristics of the synthesised materials were characterised by elemental analysis, Fourier transform-infrared spectroscopy, scanning electron microscopy, and vibrating sample magnetometer. This hybrid Fe3O4@MIP-ChCl-BuIM material was used as a magnetic adsorbent for efficient and selective removal of naproxen from wastewater samples. A batch adsorption study showed that adsorption of naproxen onto the multilayer surface of the adsorbent through a chemisorption mechanism. The data showed that the adsorption was feasible, spontaneous, and exothermic. The Fe3O4@MIP-ChCl-BuIM removed more naproxen (93.2–97.1%) than Fe3O4@MIP without ChCl-BuIM (83.2–88.9%). This finding confirms that the use of ChCl-BuIM improved both the selectivity and affinity of the MIP adsorbent towards naproxen. Competitive recognition studies of the Fe3O4@MIP-ChCl-BuIM using naproxen and structurally similar non-steroidal anti-inflammatory drugs revealed that the Fe3O4@MIP-ChCl-BuIM had high selectivity for naproxen. A cytotoxicity test showed that the synthesised ChCl-BuIM was non-toxic, as the human normal cell lines MCF-10A, and BEAS-2B maintained viability above 50%. These results show that Fe3O4@MIP-ChCl-BuIM has potential for use as a functional adsorption material for the removal of naproxen from water samples.

Engineered biochars from organic wastes for the adsorption of diclofenac, naproxen and triclosan from water systems

Abstract The increased volume of produced toxic sewage sludge requires suitable management and utilization. Biochar production is an eco-efficient technology that uses toxic wastes towards highly efficient materials in pharmaceuticals removal from water. The management of sewage sludge towards engineered biochar can solve several problems: waste volume minimalization and obtaining of the novel highly efficient sorbents. The objective of this work was an evaluation of the affinity of sewage sludge-derived biochars towards selected pharmaceuticals in water systems. In order to achieve high specific surface area and high carbon content of biochar different carrier gas conditions, preparation temperatures and different raw materials were tested. The maximum adsorption capacity was following: diclofenac - 92.7 mg/g; triclosan - 113 mg/g and naproxen - 127 mg/g. The best fitting of the experimental results revealed mainly pseudo-second order model. The adsorption of diclofenac can occur via π-stacking interactions with the biochar surface mainly via Dubinin-Radushkevich model. Both interactions between the phenyl groups of triclosan molecules and phenol groups on biochar via hydrogen bonding, and non-covalent π-π stacking of aromatic groups of triclosan and biochar were responsible for monolayer surface coverage. The adsorption of naproxen was ascribed to Langmuir, Temkin and Dubinin-Radushkevich models and strong π–π electro-donor-acceptor interactions.

Electro-assisted naproxen adsorption followed by its electrodegradation and simultaneous electroreactivation of the activated carbon electrode

In this work, the adsorption of a pharmaceutical pollutant, Naproxen (NPX), on activated carbon electrodes was improved through electroadsorption treatment under anodic polarization. After that, the contaminant was electrochemically degraded favoring the reactivation of the adsorbent material. The electroadsorption tests were performed with selected anodic potentials up to 1.1 V vs. NHE. The NPX removal increased from 14.2 mg/g (32.3%), during adsorption without electric potential, to 18.3 mg/g (42.7%) and 20.3 mg/g (47.1%) at 0.7 and 1.1 V vs. NHE, respectively, at an initial NPX concentration of 10 mg/L, in 0.05 M KNO3 solutions at pH 7. The presence of NPX on the electrode was confirmed by differential pulse voltammetry. The electrochemical oxidation of NPX followed an ECE mechanism confirmed by the analysis of voltamperometric parameters. The degradation mechanism was studied at different electrolysis times whose products were extracted by solvent and analyzed by HPLC-MS. Additionally, the reuse of the electrode was studied by the analysis of its textural properties, surface chemical analysis and in a new electroadsorption process. It was observed that the reactivated electrode increased its adsorption capacity up to 38 mg NPX/g (83 %) at 0.7 V and 41 mg NPX/g (84 %) at 1.1 V.

Acid-modulated zirconium based metal organic frameworks for removal of organic micropollutants

Abstract UiO-66 is one of the most applied metal organic frameworks on environmental remediation. In this study, UiO-66 was prepared and modified it by acid treatment. Acid treatment causes defected sites in the crystals. These defected sites provide increasing the adsorption capacities of crystals. The surface properties of prepared UiO-66 crystals were examined by X-ray diffraction spectroscopy (XRD), Fourier transform Infrared spectroscopy (FTIR), BET surface area analysis, particle size distribution analysis, and Scanning electron microscopy (SEM), respectively. 2,4-dichlorophenoxy acetic acid (2,4-D), ciprofloxacin (CPX) and naproxen (NPX) were adsorbed on UiO-66 crystals. Some adsorption variables were examined. These variables are amount of adsorbent, pH of adsorbate solution, initial adsorbate concentration, and contact time. The equilibrium times were determined as 120 min for 2,4-D, 45 min for CPX and 120 min for NPX. Pseudo second order (PSO), fractional power and Elovich kinetic models were calculated. Additionally, Langmuir, Freundlich, Sips and Radke-Prausnitz isotherms were also calculated. PSO kinetic model has been suited the adsorption of all three micropollutants. Langmuir isotherm has been fitted to 2,4-D, CPX and NPX adsorption. The calculated maximum adsorption uptake values of 2,4-D, CPX and NPX are 370.37, 111.71 and 43.86 mg/g, respectively.

Activated carbon embedded alginate beads for removing nonsteroidal anti-inflammatory drug naproxen from wastewater: equilibrium, kinetics, thermodynamics, desorption, and reusability.

In the present study, activated carbon/alginate (AC/ALG) beads were successfully synthesized with different AC:ALG ratios of 1.0-3.0 (w/v) and used for the adsorption of the nonsteroidal anti-inflammatory drug naproxen from wastewater. The beads were characterized by Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), and Brunauer-Emmett-Teller (BET) analysis, and adsorbent dosage, initial pH, initial naproxen concentration, and contact time in removal efficiency were investigated. Maximum naproxen removal percentage was achieved using 350 mg of AC/ALG beads with a ratio of 3.0% (w/v) within six hours and naproxen removal performance was determined to be 98.0%. Freundlich, Temkin, and Dubinin-Radushkevich (D-R) isotherm models were fitted to the equilibrium data better than the Langmuir model. According to kinetics results, the equilibrium time for the AC/ALG beads was reached in four hours and the kinetic model was determined by the pseudo-second-order equation. The thermodynamic parameters were calculated and enthalpy of naproxen adsorption was found to be positive for all AC/ALG beads. After the adsorption process the beads can easily be regenerated by ethanol and reused within seven cycles.

Peanut shells-derived biochars prepared from different carbonization processes: Comparison of characterization and mechanism of naproxen adsorption in water

The ubiquitous appearance of nonsteroidal anti-inflammatory drugs (i.e., naproxen) in water bodies has raised enormous concerns among general public. Development of promising materials for eliminating such contaminants from water environment has attracted much attention in the scientific community. In this study, three (direct, post-treated and pre-treated) methods were developed to prepare biochars (800-PSB, 800-800-PSB, and 190-800-PSB, respectively) derived from the wastes of peanut shells (PS). They were thoroughly characterized by various important properties (i.e., porosity and superficial functional group) and applied to remove naproxen drug from water. Results indicated that although the pre- and post-treatments had a slight effect on the surface area of biochars (i.e., 571 m2/g for 800-PSB, 596 m2/g for 800-800-PSB, and 496 m2/g for 190-800-PSB), such treatments remarkably improved the adsorption capacity of biochar. The maximum adsorption capacity of biochar (obtained from the Langmuir model) towards naproxen in solution at 25 decreased in the following order: 800-800-PSB (324 mg/g) > 190-800-PSB (215 mg/g) > 800-PSB (105 mg/g). The thermodynamic study demonstrated that the adsorption was spontaneous and exothermic. Depending the preparation process, the contribution of each mechanism in the adsorption process was dissimilar. The overall adsorption mechanism was regarded as pore filling, π-π interaction, hydrogen bonding formations, n-π interaction, van der Waals force, and electrostatic attraction. Two methods used to identify the important role of π-π interaction were proposed herein. The possible desorption and reuse of laden-biochars were investigated by the chemical and thermal methods. The prepared biochar samples can serve as potential carbonaceous porous adsorbents for effectively removing naproxen from water media.

Experimental investigation of competitive co-adsorption of naproxen and diclofenac from water by an aluminum-based metal-organic framework

Commercially available Aluminum-benzenedicarboxylate (Basolite A100, MIL-53 (Al)), Metal-Organic Framework was successfully used for the adsorption and co-adsorption of Naproxen (NAP) and Diclofenac (DCF) from aqueous solutions. The adsorption experiments were carried out using single-component NAP/DCF and their binary aqueous solutions. The experimental results demonstrated the remarkable removal efficiency of the MOF (>96% for NAP and >99% for DCF). Besides, the competitive adsorption of the drugs from binary solutions showed higher selectivity toward DCF. The hydrogen bonding and π-π stacking were investigated to gain insight into the adsorption mechanism. The pH effect experiments in the range of 2 to 8 showed that as pH increased, the adsorption capacity of both drugs decreased. The fitting of the adsorption isotherm and kinetic models confirms that both contaminants conform to the Langmuir model and pseudo-second-order (PSO) models with high regression coefficient ( R 2 > 0.99). The PSO rate constant values for NAP were 0.0056 (single-component) and 0.0024 g·mg −1 ·min −1 (binary), while for DCF these values were 0.0037 (single-component) and 0.0014 g·mg −1 ·min −1 (binary). According to the isotherm model, the calculated maximum removal capacities ( q m ) values were found equal to 297 and 422 mg/g for NAP and DCF, respectively. The suitability of MIL-53(Al) for adsorption of naproxen and diclofenac in mineral water was also investigated. Finally, MIL-53(Al) was confirmed to be a promising adsorbent candidate thanks to its highly efficient removal of NAP and DCF in both single and binary solutions and then can be deployed in water treatment. • MIL-53(Al) showed great potential for water purification from pharmaceuticals. • MIL-53(Al) had better selectivity for DCF compared to NAP. • Adsorption mechanism was determined to be due to hydrogen bonding and π-π stacking. • The experimental data fitted best the Langmuir isotherm and PSO kinetic models. • The maximum adsorption capacities' values were found equal to 297 and 422 mg/g for NAP and DCF, respectively.

Kinetic and thermodynamic analysis of adsorption of naproxen by activated sludge

Naproxen, a new environmental drug pollutant, shows “false persistence” in the environment and causes certain risks to human health and ecological environment, which has attracted extensive attention. The activated sludge in the sewage treatment technology plays a significant role in the control of the naproxen content. This paper carried out the kinetics and thermodynamic analysis of the adsorption process of naproxen by activated sludge. The experimental results show that the adsorption process of naproxen by activated sludge conforms to the pseudo-second-order kinetic equation and the linear fitting R2 value is more than 0.99 at different initial concentrations. The Freundlich equation and Langmuir equation were adopted to carry out the adsorption models fitting. The Freundlich equation could represent the adsorption results satisfyingly. There is a negative correlation between the initial concentration of naproxen and the adsorption rate. The adsorption effect is determined by the hydrophobicity of naproxen and the electrostatic reaction between naproxen and activated sludge. After adsorption, there is no obvious naproxen desorption in activated sludge.

Naproxen Removal Capacity Enhancement by Transforming the Activated Carbon into a Blended Composite Material

The naproxen adsorption capacity enhancement of activated carbon prepared from the Indian gooseberry seed-shells by manufacturing a composite blended with the surface-modified graphite powder and silver nanoparticles was studied in the present context. The composite of the nano-sized materials was prepared in dimethylformamide solution and characterized by employing XRD, Raman, EDS and FT-IR spectroscopy, FETEM, and FESEM microscopy. The pseudo-first-order, pseudo-second-order, and Elovich models were applied to test the removal kinetics. Preliminary results were also fitted to the Langmuir, Freundlich, Temkin, and Dubinine-Radushkevich (D-R) adsorption isotherm models to determine the specific parameters of each model. The effects of the initial pH of the solution, naproxen concentration, and contact time on the process were optimized. The maximum adsorption capacity was obtained as 154.98 mg g−1 (61.99%) with an increment of 25.31% by the addition of surface-modified graphite powder and silver nanoparticles at the optimized experimental conditions.

Preparation of activated carbon from water hyacinth stems by chemical activation with K2CO3 and its performance as adsorbent of sodium naproxen

AbstractActivated carbons were obtained from water hyacinth stems using K2CO3 as activation agent, varying the impregnation time and the activation temperature and time, accordingly to a 23 factorial experimental design. The produced carbons showed activation yields (8–20%), alkaline point of zero charge (average of 9.5), methylene blue indexes from 264 to 893 m2/g, carboxylic surface groups in major proportion and graphitization degree from 4.01 to 6.27%. According to the statistical analysis, the activation temperature was significant for the yield and the methylene blue index. Activated carbon, labeled as AC5, was selected to assessing the naproxen adsorption in aqueous solution. Batch experiments yielded maximum adsorption capacity of 77.44% at pH ≈ 10.3, and contact time of 8 hr at initial concentration of 40 mg/g. The adsorption kinetics, isotherm model, and diffusion mechanism were described by the pseudo‐second order model, the Redlich‐Peterson equation and the film diffusion, respectively.

Preparation of poly(4-vinylpyridine)-functionalized magnetic Al-MOF for the removal of naproxen from aqueous solution

In this work, a novel poly(4-vinylpyridine)-functionalized magnetic Al-MOF (Al-MOF-Fe3O4@P4VP) was synthesized successfully as an adsorbent for the adsorption of naproxen from aqueous solution. The resulting adsorbent was characterized with scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, vibrating sample magnetometer (VSM), BET surface area and X-ray photoelectron spectroscopy (XPS). Al-MOF-Fe3O4@P4VP had high surface area (123.68 m2/g), porous structure, rough surface and magnetic property. The maximum adsorption capacity of Al-MOF-Fe3O4@P4VP for naproxen could reach up to 31.67 mg/g and the adsorption process was well described by the Freundlich isotherm. The adsorption rate of naproxen on Al-MOF-Fe3O4@P4VP was very fast and the kinetics could be well modeled by the pseudo-second-order model. The adsorbent exhibited good adsorption ability even after ten adsorption-desorption cycles. Al-MOF-Fe3O4@P4VP had the characteristics of high removal efficiency, fast adsorption speed, good reusability and easy separation, making it a novel environment-friendly and effective magnetic nanomaterial in adsorbing naproxen from wastewater.

Kinetics and thermodynamics of NPX adsorption by γ-FeOOH in aqueous media

Naproxen (NPX) is a common PPCPs in wastewater treatment plants which is influenced by the coexistence on its photodegradation. Most research on reasons for NPX photodegradation has focused on the soluble substances in water mainly, and the adsorption effect of solid particles is less. The effects of initial concentration, temperature, and pH on the adsorption of NPX on γ-FeOOH were studied. It was found that the equilibrium time of γ-FeOOH adsorbed NPX was 240 min. The increase of initial concentration and temperature were favorable for the adsorption. The optimal adsorption pH was 7.0, and the adsorption capacity attained 28.05 mg·g−1. It was learned, through model fitting, that the adsorption reaction was in accordance with the Laggenren quasi-second-order kinetic model; the internal diffusion process was the control step, where the adsorption was close to the Langmuir isothermal adsorption model. The thermodynamic calculation showed that ΔG < 0, ΔH < 0, ΔS < 0, which inferred that the adsorption was a spontaneous, endothermic, and entropy increasing process, which is the common action of chemical bond forces and static electricity.

Adsorptive removal of anti-inflammatory drugs from water using graphene oxide/metal-organic framework composites

Highly porous metal-organic framework (MOF) composites were synthesized by combining MIL-101(Cr) with graphene oxide (GnO). The porosity of the GnO/MIL-101 composite was increased by composing GnO onto the MOF up to a certain ratio. The GnO/MIL-101 composites were utilized to adsorb anti-inflammatory drugs (AIDs) such as naproxen (NAP) and ketoprofen (KTP) from water. It was observed that GnO/MIL-101 composites displayed highly improved adsorption toward both NAP and KTP relative to pristine MIL-101 and commercial AC. MIL-101_GnO(3%) had a NAP adsorption capacity 2.1 and 1.4 times those of commercial AC and pristine MIL-101, respectively; its adsorption performance was also very competitive with other reported adsorbents. The improved adsorption performance of the composites for NAP was credited to H-bonding because of the presence of several functional groups in the composites. MIL-101_GnO(3%) and NAP act as a H-bond donor and acceptor, respectively. Moreover, MIL-101_GnO(3%) can be regenerated without severe deterioration by simple ethanol washing and can be reused for successive adsorption. Therefore, the GnO/MIL-101 composite is suggested as an efficient adsorbent for the removal of AIDs from water.

Comparison of different polymeric resins for naproxen removal from wastewater

The polymeric resins are eco-friendly, cheap and have good surface properties. These resins were used for Naproxen (NPX) adsorption from aqueous solutions. Three different resins were chosen. These are Amberlite XAD-2, XAD-4 and XAD-16. The effects of adsorption variables were tested. The variables were selected as adsorbent quantity, NPX concentration, pH of solution, temperature and contact time. Langmuir and Freundlich isotherm models were applied to the experimental data. And it was observed that Langmuir isotherm model fitted the experimental data properly. The pseudo second order kinetic model and Weber-Morris intraparticle diffusion model were used for kinetic analysis of NPX adsorption. The pseudo second order model was the best fitted kinetic model for NPX adsorption. The rate-controlling step was determined as the intraparticle diffusion step. The NPX adsorption on Amberlite resins was exothermic process. According to isotherm parameters, separation factor (RL) values, kinetic and thermodynamic data, XAD-4 was found to be the most suitable adsorbent for NPX adsorption. Amberlite XAD-4 reached the maximum removal percentage (99.88%) at 0.5g of adsorbent. NPX adsorption capacity of XAD-4 was 6.52mg/g at 308K, according to Langmuir isotherm model.

Surface-mounted MOF templated fabrication of homochiral polymer thin film for enantioselective adsorption of drugs.

A self-polymerized chiral monomer 3,4-dihydroxy-l-phenylalanine (l-DOPA) has been introduced into the pores of an achiral surface-mounted metal organic framework (SURMOF), and then the homochiral poly(l-DOPA) thin film has been successfully formed after UV light irradiation and etching of the SURMOF. Remarkably, such a poly(l-DOPA) thin film exhibited enantioselective adsorption of naproxen. This study opened a SURMOF-templated approach for preparing porous polymer thin films.
