Abstract
本申请是关于一种利用苯芴酮分光光度法检测锌电解液中锗含量的方法，属于锗的检测技术领域。包括以下步骤：S1、样品预处理：移取一定体积的电解锌液待测样品于比色管中，加入浓度为4‑5%的硝酸溶液进行预处理；S2、显色反应：向经过预处理的样品中加入磷酸与聚乙烯醇水溶液的混合液，混匀后，再加入0.3 g / L的苯芴酮显色液，蒸馏水定容，摇匀后避光放置进行显色反应；S3、测定与计算：用分光光度计在波长520nm处测定显色后溶液的吸光度，用试剂空白作参比，根据预先绘制的工作曲线计算所述电解锌液中锗的含量。该方法分析结果准确度和精密度较高，在实际生产分析检测中可操作性强，操作简便、快速，可以较好地满足生产上对快速准确分析的要求。
