The Performance of Different AgTiO2 Loading into Poly(3-Nitrothiophene) for Efficient Adsorption of Hazardous Brilliant Green and Crystal Violet Dyes

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.

“…6–8 Among these methods, adsorption as a widely available and highly efficiency method is promising for the treatment of wastewater, and it is often used to eliminate different dyes from water. 9–11 Many adsorbents, including activated carbon, silica, metal oxides, and polymer resins, have been developed. 12–16 However, most of the prepared materials suffer from lower adsorption efficiencies and leaching of the active species.…”

“…For many decades, adsorption process has been the most famous and most used wastewater treatment technique for removing aqueous pollutants 33 – 35 . Recently, the removal of CR 36 , 37 , BG 38 , 39 , MB 40 , 41 , and MR 42 , 43 from colored aqueous solution was conducted successfully. PA-12 is new in the area of environmental science.…”
