The research established the continuous determination method for lead and  gold  in precious lead.The samples are dissolved with nitric acid and bromine.Lead sulfate precipitation is generated by adding sulfuric acid,sepa-rating lead from gold and impurities.Acetic acid-ammonium acetate dissolves lead sulfate.And lead content is determined by Na₂EDTA titration;gold content is determined by flame atomic absorption spectrometry after ashing-alkali dissolution or ashing-aqua regia dissolution.When lead content is determined,the method has a RSD of 0.12 %,the recovery rate of reference materials 92.10 %-96.42 %;when gold content is determined,the RSD is 0.20 %-0.52 %,the recovery rate of reference materials is 90.20 %-97.20 %.The method has good accuracy and precision and is consistent with the requirement of analysis and determination.
