Applications of polyaniline-impregnated silica gel-based nanocomposites in wastewater treatment as an efficient adsorbent of some important organic dyes

Abstract Due to a recent lack of clean water as result an increasing demand, new wastewater solutions are required. Many researchers have looked into the removal organic dyes from wastewater, with adsorption being easy and effective method for removing inorganic contaminants contaminated water. Conjugated modified polymers, primarily polyaniline (Pani), been widely used in treatment because their unique properties, such synthesis, tunable morphology, porous structure, good electrorheological property, biodegradability, nontoxic nature. Modified surface polymers more reactive outstanding dye capabilities treatment. This review article elaborates on by utilizing silica gel-impregnated nanocomposites adsorbents. The use polyaniline-modified gel migration behavior most suited system resolution co-existing is referred separation mixtures. Adsorption important optimize conditions efficient comparison another commercially available adsorbent. Chemical modification introduction acidic or basic functionality could increase cationic anionic chemical adsorption, well charged species dyes. carrier thus obtained chelating reagent after impregnation polyaniline.
