1.引言铑络合物在催化、有机合成制药、新能源的开发方面有广泛的应用。醋酸铑、二氯四羰基铑及一氯三(三苯膦)铑、一溴三(三苯膦)铑络合物均是其它铑络合物的主要原料或作为催化剂。Barclay和Broadbont认为用热分解法有可能解决含氮铑络合物中铑的定量测定。而对磷砷配位体的络合物是困难的。文献曾用萃取分光光度法测
1. Introduction Rhodium complexes are widely used in the fields of catalysis, organic synthesis pharmaceuticals and new energy sources. Rhodium acetate, dichlorotetracarbonyl rhodium and trichlorophosphite rhodium, bromine tris (triphenylphosphine) rhodium complex are the main raw materials for other rhodium complexes or as a catalyst. Barclay and Broadbont believe that it is possible to solve the quantitative determination of rhodium in nitrogen-containing rhodium complexes by the thermal decomposition method. Complexes with phosphorus arsenide ligands are difficult. The literature was measured by extraction spectrophotometry
