摘要
主要研究了锌电解生产过程中新液、电解液中痕量锗的准确稳定分析方法。结果表明：在20%的磷酸溶液中,用标准加入法,原子荧光光谱仪测定新液、锌电解液中的锗,对同一样品进行8次测定,其相对标准偏差为5.3%,锗的加标回收率为95.6%~102.0%,结果稳定可靠,能满足生产要求。
An accurate and stable analysis method for the determination of trace germanium in zinc electrolyte and new electrolyte in the process of zinc electrolysis was investigated in this paper. The results indicated that germanium in zinc electrolyte could be determined by standard addition method using atomic fluorescence spectrometry in 20% phosphoric acid solution. The relative standard deviation for eight replicate measurements was 5.3% with 95.6~102.0% recovery. The method is stable and reliable, and can meet the production requirement.
