摘要
本文探讨了钐离子在弱酸性介质中与偶氮胂Ⅲ反应生成稳定络合物的最佳条件，提出了直接在水相中测定钐的分光光度法．本方法简便、快速、准确，适用于镀液和镀层中钐含量的快速测定．
The optimum conditions for forming a stable complex by samaric ion with arsenazo Ⅲ in a weak acid medium are investigated. A spectrophotometric method for determining of samarium in water phase are given. This method is simple, rapid, convenient andaccurate. It can be used in the rapt(1 tletermination of samarium content in electroplating solution or electroplated layer.
