摘　　要：建立了火焰原子吸收光谱法(FAAS)测定锡阳极泥中银含量的方法。文章考察了不同的测定介质、酸度对测定结果的影响。实验结果表明在选定条件下,锡阳极泥中的锡、锑、铅等杂质不干扰银的测定。方法加标回收率在99.2%~103%,精密度实验结果表明,相对标准偏差(RSD,n=11)均小于4%。操作过程简单,能满足生产的需要。A method for the determination of silver in tin anode slim by flame atomic absorption spectrometry （FAAS） was developed. The effects of media and acidity on the determination were investigated. Under the selected conditions, the impurities such as tin, antimony and lead in tin anode mud did not interfere with the determination of silver. Values of recovery were in the range of 99.2% to 103% and the result of precision test showed that RSD（n=11） was less than 4%. This method is simple and can meet the testing requirements for daily analysis of impurity elements in tin anode slime.
