摘要: Acrylamide (AAm)-2-acrylamide-2-methylpropanesulfonic acid sodium salt (AMPSNa) hydrogel and AAm-AMPSNa/clay nanocomposite having 10 w% clay was prepared by in situ copolymerization aqueous solution the presence of a crosslinking agent (N,N′-methylenebisacrylamide (NMBA)). Swelling properties kinetics samples were investigated water solutions Safranine-T (ST) Brilliant Cresyl Blue (BCB) dyes. The swelling diffusion parameters also calculated dye solutions. It observed that exhibits improved capacity compared with AAm-AMPSNa hydrogel. found mechanisms show non-Fickian character. Adsorption ST BCB dyes investigated. Clay incorporation into structure increased not only adsorption but rate. values to be 484.2 494.2 mg g−1 for dyes, respectively. seen completed 10 min while adsorbed approximately 90 min. data modelled pseudo-first-order pseudo-second-order kinetic equations order investigate mechanism. followed model.
