Abstract:

Chitin present in fish scales was 52% deacetylated into chitosan by treating with 4% Sodium Hydroxide. The cation exchange properties of this chitosan were studied for some first row divalent transition metal ions at different molarities of Sulphuric Acid. The distribution coefficient and the apparent adsorption capacity have been determined. Following selectivity order has been established:Cu2+ > Ni2+ > Co2+ > Fe2+.
