建立了以2mol/L乙酸为吸附溶液的巯基棉分离富集铅锭中银的方法，对Pb=Ag=1×106:1样品中的铅、银分离取得良好的效果，与火焰原子吸收光谱法相结合，测定标准加料试验的回收率为95．17％～100.18％，对子铅锭中含量为0．0001％～0．006％的银，变异系数为1．72％～4．90％．
A method for the separation and enrichment of silver in the lead ingot by mercapto-cotton with 2 mol / L acetic acid as the adsorption solution was established. The results showed that Pb and Ag in the sample with Pb = Ag = 1 × 106: 1 were separated well and the results were in good agreement with flame atomic absorption spectrometry The recoveries were 95.17% ~ 100.18% for standard feed tests and 1.72% ~ 4.90% for silver from 0.0001% to 0.006% for lead ingots.
