Abstract

The in-situ polymerization technology was used to successfully produce nanostructured binary nanocomposites (NCs) made from a poly (3-nitrothiophen) matrix (P3NT) that were loaded effectively with nanoparticles (NPs) of silver titanium dioxide (AgTiO2), of varying percentages (10%, 20%, and 30%). A uniform coating of P3NT covers the AgTiO2 NPs. Various methods were performed to confirm the fabrication of the binary P3NT/AgTiO2 NCs adsorbents, such as FTIR, XRD, SEM, and EDX. Both dyes (brilliant green (B.G.) and crystal violet (C.V.)) were removed from liquid media by using the binary P3NT/AgTiO2 NCs. A range of batch adsorption studies was used to optimize various factors that impact the elimination of B.G. or C.V. dyes, including the pH, weight of the binary P3NT/AgTiO2 NC, proportion of AgTiO2 NP, time, and temperature. The pseudo-second-order kinetics ( R 2 = 0.999 ) was better adapted for the adsorption procedure’s empirical data whereby the maximum adsorption capacity of the C.V. dye was 43.10 mg/g and ( R 2 = 0.996 ) the maximum adsorption potential was 40.16 mg/g for B.G. dye, succeeded by the pseudo-second-order kinetics. Moreover, the adhesion of B.G. and C.V. pigments on the layers of NCs involves an endothermic reaction. In addition, the concocted adsorbent not only exhibited strong adsorption characteristics during four consecutive cycles but also possessed a higher potential for its reuse. According to the findings, the NCs might possibly be used as a robust and reusable adsorbent to remove B.G. and C.V. pigments from an aqueous medium.

Summary

Introduction

The unending discharge of pollutants in the environment has positioned water pollution amongst the few topmost environmental issues. Brilliant green (B.G.) dye is a cation that has a triphenyl nitrogen structure, which is used in veterinary medicines, biopigmentation, the coloring of textiles, manufacturing of ink for colored printers, and dermatological products in the form of a supplement to chicken food for regulating the growth of parasitic organisms and fungi [7] It tends to initiate a multitude of health issues, including cough, diarrhea, difficulty in breathing, nausea, vomiting, and painful flushes [8]. A novel, highly effective, and affordable, innovative adsorbent is created in this research by using an insitu chemical polymerization technique to combine P3NT with various loads of AgTiO2 This conglomerate incorporates the benefits of every component, as a result of which the adsorption efficiency of recommended adsorbents enhances because of increased active points on the backbone of the polymer string, which leads to a higher capacity of dye elimination. A multitude of factors, including pH, heat, time of shaking, time, mass, and effect of ionic power, influencing the process of elimination of dyes was examined, after which the data of adsorption was scrutinized with the help of multiple thermodynamic and kinetic criteria
