Abstract: Naturally occurring polymers such as carrageenan and chitosan were used for the synthesis of hydrogel using glutaraldehyde as the crosslinking agent. Characterisation of chitosan and carrageenan based hydrogels for PH sensing, urea adsorption and dye adsorption were conducted. Different compositions of carrageenan-chitosan hydrogels were formulated and optimised the best compositions based on the maximum urea adsorption at hydrogel which can be employed for PH sensing, urea adsorption and dye adsorption. These hydrogels were used in several agricultural, textile industry and biomedical applications.
