dc.descriptionChitosan was obtained from shrimps shells (pleuroncodes monodon) using chemical methods. A series of chitosan (QS)charged with solution of copper, cobalt, nickel and mercury ions were prepared at room temperature using the batch method. N-3,5-diethylamino benzoyl chitosan (QDAB); N,O-dimercapto succinate chitosan (QNOT) and 4-aminobenzoate chitosan (QAB) derivatives were prepared. The chitosan metal adducts with Cu, Co, Ni and Hg ions and derivatives maximum loading is discussed. Chitosan and derivatives containing copper were analyzed by SEM to find out the morphology of the polymers. Chitosan-Cu and derivatives charged, QDAB-Ni and QDAB-Hg were analyzed by EDX to verify the presence of the metal in the polymeric chain
