chitosan based material for copper and phosphate removals

Experimental methodologycopper removal by chitosan beads —-( copper sulfate pentahydrate solution are used)1- equilibrium study2- kinetic study3- ph study4- contact time study5- regeneration study– phosphate removal ( orthophosphate solution ) using copper chitosan beads after copper adsorption1- effect of copper loaded concentration2- effect of another anion like ( chloride, sulfate, and nitrate) on adsorption of orthophosphate3- equilibrium study4- kinetic study5- ph study6- regeneration study
