采用火焰原子吸收法（ FAAS）对溶液中铑（ Rh）的含量进行分析，结果表明，选用CuSO4-LaCl3体系作为释放剂，能有效提高测定铑的灵敏度，消除常见无机酸和多种共存金属离子的干扰，实验量为每5 mL Rh溶液加入5 mg/mL CuSO4和5 mg/mL LaCl3各1 mL，加标回收率在99.85％～105.05％之间，释放剂添加量少，操作简便、快速、可靠．

The content of rhodium in solution was determined by the flame atomic absorption spectrometry method . This article studied different factors that influenced the determination of rhodium , including releasing agent , inor-ganic acid and coexistence metal ions .The result showed that the determination sensitivity of rhodium can be in-creased and the interference of inorganic acid and coexistence metal ions disappeared by adding CuSO 4-LaCl3 as re-leasing agent .The experiments indicated that the adding amount for 5 mL rhodium solution was 1 mL each of Cu-SO4and LaCl3 solutions (the concentrations were both 5 mg/mL).The recovery of standard addition ranged from 99.85%to 105.05%.The adding quantity of releasing agent in this paper is less than others .The method is sim-ple, rapid and accurate .
