A Review of Removal of Copper Ion from Wastewater in Physical-chemical Process and Sec-reclamation of Copper Ion

HU Yu-qian,HU Li-song,YU Xun-min (College of Environment Civil Engineering,Wuhan University of Technology,Wuhan,Hubei,430073,China)  
The researches and applications of copper ion removal from waste water by physical-chemical process are summarized.These processes include inorganic absorbent,organic absorbent,organic-inorganic compound material adsorption as well as biological absorbent.The main mechanisms in these processes are surface adsorption,ion-exchange,chola gathers,membrane separation and infiltration.The physical-chemical process in the removal of copper from waste water is simple,and the absorbents can be reused.And that can reduce second pollution as well as the copper may be recycled.
