摘要
选用三种常用的化学还原剂来模拟修复铬污染地区的地下水,并通过紫外可见分光光度计来检测治理后水中六价铬的残留量。同时对这三种试剂的治理效果进行平行性试验。筛选出对六价铬具有较好还原作用的还原剂是多硫化钙。
Three common chemical agents are selected to simulate the groundwater in chromium contaminated areas,and the residual amount of hexavalent chromium in the treated water is detected by UV-Vis spectrophotometer.At the same time,the effects of these three reagents are tested in parallel.Calcium polysulfide,a reducing agent with good reduction effect on hexavalent chromium is screened out.
