Removal of crystal violet dye from aqueous solution using protein-based hydrogel nanocomposite

Superabsorbent hydrogels have found wide applications in different fields, such as agriculture, tissue engineering, artificial muscles, wound dressing and as an adsoption ofwater pollutions [1-3]. In this study, a novel collagen-gpoly( acrylamid-co-maleic anhydride)/Na-montmorillonit hydrogel nanocomposite was synthesized. The effects of some parameters such as initial concentration of dye solution and contact time was investigated.
