Abstract:
In this study，a newheavy mental capturing agent DTC-U containing dithiocarbamatewassysthesized，and thetreatment efficiency ofPb2+wastewaterwasresearched．The resultsshowedthat：forwastewater containing 10 mg／LPb2+．theresidual dosage ofPb2+wasbelow0．5 mg／Lby added26 mg／L DTC-U，pH3～10，using PAC as flocculant and slower stirring for8min．Theremoval rate ofPb“from wastewatercan be achieved over95％whichwasenough to meet the request of the GB25466--2010．For the CO—existence of Pb2+andCd2+in wastewater．Pb2+was preferentially reactioncompared to Cd2+．Andtheresidual dosage of Pb2+andCd2+canmeetthe requirements of the GB25466--2010．TheDTC．U is suitable foruse in wide pH．has the favorable effectand has a good application prospect．
