研究了贵金属Ru、Rh、Pd、Au-SnCL_2-RB体系及缔和物溶剂浮选的条件,采用偏最小二乘回归法对重叠光谱进行解析及数据处理.对地质样品中Ri、Rh、Pd、Au同时测定,相对误差小于11.1%;标准偏差为0.0062～00.19.
The conditions of noble metal Ru, Rh, Pd, Au-SnCL_2-RB systems and solvent flotation were studied, and the overlapped spectra were analyzed by partial least squares regression. , Au simultaneous determination, the relative error of less than 11.1%; standard deviation of 0.0062 ~ 00.19.
