Abstract

When use Sn to deoxidize Sb(Ⅲ) or Sb(Ⅴ) to identify Sb,Hg2+Ag+BOECu2+ always interfere.Experiments find that using N-allyl-N′-(sodium-p-benzenesulfonate) thiourea can eliminate the interference of Hg2+Ag+ andCu2+ at the same time.Compared with the traditional sedimentation method,this method is easier,simpler to operate and more effective.
