Abstract
Dithiocarhamates (DTC) have a strong ability of chelating heavy metals.In order to see the adsorptivity of DTC to Cd, this thesis conducts experiments using DTC to capture cadmium in waste water that contains Cd 37.00 mg/L; meanwhile, it also explores the influence of several factors such as reaction time, the content of capturing agent, pH value and coexistence of other heavy metals on DTC's capture efficiency.The conclusion is that it has the best capture effect when pH is 5-11 and cadmium (cd) per gram using 40 mg capturing agent.There is no significant influence when cuprum (Cu) and plumbum(Pb) coexist with cadmium.The removal rate of waste water containing Cd 37.00 mg/L can be more than 99.9％ when pH is 7-9 , which can reach national wastewater discharge standard after treatment.关键词
