Abstract :
Zinc ion in supplying water is in low concentration. Permutite and chitosan are of safety and efficiency in metal ions adsorption. The article combines the two materials together with 2% acetic anhydride solution and it increase the efficiency of adsorption better than with deionized water, also than permutite and chitosan. Rotator speed was proved to be the most effective factor for low concentration ions adsorption. Results of stability, and homogeneity investigated by SEM and FTIR are positive. It decreases the ions of zinc in low concentration by 99% in 80 minutes, outbalance to pure permutite and chitosan.
