%X Amacromolecular flocculant for heavy metals,mercaptoacetyl chitosan(MAC),was prepared by reacting chitosan with mercaptoacetic acid.In preliminary experiments,the flocculation performance of MACwas evaluated by using wastewater which contained Cu2+ and/or turbidity.Factors which affect the removal of Cu2+ and turbidity were studied and the experimental results showed that,1MAC can remove both Cu2+ and turbidity from wastewater.The removal rate of Cu2+ by using MAC combined with anionic polyacrylamide is higher than that with MAC,the removal rate of Cu2+ reaches above 98%;When the water sample contained not only Cu2+ but also turbidity-causing substances,the removal rate of both Cu2+ and turbidity was promoted by the cooperative effects of each other,leaving a residual concentration of Cu2+ below 0.5 mg·L-1 and the turbidity below 3NTU.Thus,Cu2+ is more easily removed by MAC when the water is more turbid;The removal rate of Cu2+ increases when the pHvalue increased(from 4.5 to 5.5),contrarily the removal rate of turbidity decreases at higher pH.
