    • Abstract
  • Hydrochloric acid, nitric acid and sulfuric acid are employed in the sample decomposition, forming lead sulfate precipitation with zinc separation.The content of zinc in the filtrate is determined with EDTA complexometric titration method by using slow filter paper filter.Sedimentation with HNO3 (1+1) is dissolved in the buffer solution of acetic acid-sodium acetate with pH5.5~6.0, with xylenol orange as indicator titration by applying EDTA standard solution of lead.
