Synthesis of PANI@ZnO Hybrid Material and Evaluations in Adsorption of Congo Red and Methylene Blue Dyes: Structural Characterization and Adsorption Performance

In this research, a simple oxidation chemical process was applied for the synthesis of novel PANI@ZnO nanocomposite. The prepared nanocomposites were characterized by XPS, XRD, FTIR, SEM, TGA and N2 adsorption–desorption isotherms. Thereby, highest SBET values (about 40.84 m2 g?1), total mesoporous volume 3.214 cm3 g?1) average pore size 46.12 nm). Afterwards, nanomaterial as nanoadsorbent adsorption Congo Red Methylene Blue dyes from aqueous solutions at 298 K pH 5.0. Besides, pseudo-second-order model obtained best both dyes. case isotherm models, Freundlich showed fit. After removal, spent adsorbent regenerated. With regeneration repeated five cycles, efficiency remained very adequate level. These results are heartening in respect with objective to utilize them field sensors technology research related photoluminescence sensor application.
