原始语种摘要: At present, the problem of heavy metal pollution is a hot topic in the world. There are significant differences in the types and concentrations of metal ions distributed in each contaminated sites. In China, due to the vast territory and diverse ecoenvironments, the pollution situation is complex and variable, and the composite pollution is particularly obvious. Overall, pollution in the southern provinces is relatively higher than in other provinces, and Cd, Hg, Pb, Cr, As and Ni are listed as the priority pollutants for control. The metals have different physical or chemical specificity that allows them to be treated differently. Toxic Cr(VI) needs to be reduced to non-toxic Cr(III) before removal, whereas Cd(II) can form an insoluble Cd compound precipitate under alkaline conditions....
