摘要
在聚乙烯醇（PVA）存在下，铑（Ⅲ）与钼酸盐和破性染料（罗丹明B，乙基罗丹明B，耐尔蓝）形成离子缔合物，并研究四个显色体系的光度特性和40多种共存离子的影响，此方法用于冶金产品中铑的测定，结果满意．
A highly sensitive spectrophotometric method for the determintion of rhodium has been studied, based on the reaction of rhodium with molybdate and basic dyes to form an ion associntion complex in the presence of polyvinyl alcohol, The molar absorptivities ate 1.68×105, 3.22×105, 6.69×105 and 1.80×105L. mol-1. cm-1. Suitable condition for the reactions,the effects of foreing and composition of complexes were investigated, The methods can be applied to the spectrophotometric detrmination of trace amounts of rhodium in some metallurgical products.
