The Experimental Study of Treatment on Wastewater Containing Cadmium With Macromolecule Chelating Agent

The influences of macromolecule chelating agent seizing Cd2+ are determined by pH,quantity of macromolecule chelating agent,sediment time and system temperature.the concentration of chelating agent 1%(w/v): 0.7ml solution;pH value: from 6 to 9;sediment time: 30 min;system temperature: 30℃,20 mg/L macromolecule chelating agent has the optimum technological parameter.
