RETENTION CAPACITY OF CHITOSAN FOR COPPER AND MERCURY IONS

Chitosan, was obtained from red lobster shells (Pleuroncodes monodon). The Mv of chitosan prepared was 54.000 g/mol with a deacetylation degree of 20%. The retention capacity of chitosan for copper and mercury ions was studied. The adsorption isotherms of Cu(II) and Hg(II) and the mixture of ions ar...
