摘　　要：采用胶束增溶-偏最小二乘回归光度法在 BRB-SnCl_2-AG-OP 离子缔合物体系中,对锇、钌同时测定进行了研究.结果表明,该方法的灵敏度高,其表观摩尔吸光系数分别为1.32×10~6, 2.30×10~6;相对标准偏差(RSD)分别为3.54%及2.87%;模拟样品分析的相对误差均小于10%;该方法可不经蒸馏分离同时测定锇、钌。Simultaneous determination of precious metals Ru and Os has been studied with micellar solubilization-partial least squares spectrophotometric method in BRB-SnCl_2 -AG-OP ion associated system.The method has a high sensitivity, ε_(596)^(Os)=2.3×10~6,ε_(592)^(Ru)=1.32×10~6;relative standard deviation(%)are 3.54(Ru)and 2.87(Os).The relative errors are less than 10%.The method is simple and easy to operate with satisfactory results.
