摘　　要：将模糊聚类分析与偏最小二乘相结合，对锇、钌双组份重叠光谱进行解析；较好地解决了校正分析中校准模型的优化问题，提高了分析结果的准确度；研究了锇、钌－ＳｎＣｌ２－乳化剂ＯＰ－阿拉伯树胶（ＡＧ）－丁基罗丹明Ｂ（ＢＲＢ）高灵敏多元离子缔合物显色体系。锇、钌的检出限分别为 ０，６３２ μｇ／Ｌ和 ０．３６８ μｇ／Ｌ，模拟地质样品分析结果的相对误差小于±１０％。Partial least squares was applied to the simultaneous determination of Os and Ru in imitative geological sample with SnC12-buthyl rhodamine B(BRB)-emulsion OP(OP) color system. In this method, fuzzy cluster analysis was used to optimize the calibration model. The detection limit of Os anr Ru is 0.632 μg/L and 0.368 μg/L, respectively. Relative error of Os and Ru is < 10%.
