摘　　要：本文研究了铂、铑氯化亚锡络合物的重叠吸收光谱和分光光度法同时测定铂、铑的反应条件和结果的计算方法。通过计算机处理实验数据。可快速得出两组份的浓度。分析结果的相对误差不超过±1.8％。The absorption spectra of Platinum and Rhodium-Stanous Chrorid Complexes and the Optinum conditions for the Simultaneous Spectrophotometric determination of microamounts of Platinum and Rhodium are studied: A computer program is gaven and it can be used for any two components, Percentage recovery shows that the relative crror of the results abtained by this method is within ±1.8%, and the results were satisfactory.
