Chitosan-based hydrogels: bentonite supported architectures explored for removal of cadmium( ii ) from aqueous solution

Key Points

• The aim is to develop a hybrid hydrogel system that efficiently removes cadmium from aqueous solutions.
• Utilized chitosan, poly(vinyl alcohol), 3-aminopropyltriethoxysilane, and bentonite to create a hybrid hydrogel.
• Assessed the adsorption capacity for cadmium( ii ) removal from water.
• The hybrid hydrogel demonstrated high efficiency in cadmium removal.
• Results indicated a cost-effective and environmentally friendly approach.
