Carbon nanotube/Chitosan hydrogel for adsorption of acid red 73 in aqueous and soil environments
Abstract Acid red 73 is an azo dye, and its residue can pollute the environment and seriously threaten human health and life.In this study, glutaraldehyde was used as the crosslinking agent, chitosan and polyvinyl alcohol were crosslinked under appropriate conditions to obtain a chitosan hydrogel film, and carbon nanotubes were dispersed in the chi
