研究了硅胶吸附锆 BPR配合物的条件及硅胶相中配合物的组成 ,并采用固相反射散射分光光度法直接测定硅胶相中锆的含量。方法的检出限为 0 .1 3mg/L ,相对标准偏差为 4.3% ,用于矿样中锆的测定 ,回收率为 93%。
The conditions for the adsorption of zirconium BPR on silica gel and the composition of the complex in the silica gel phase were studied. The content of zirconium in the silica gel phase was determined by solid-phase reflection spectrophotometry. The detection limit of the method was 0.1 1.3 mg / L with a relative standard deviation of 4.3%. The method was applied to the determination of zirconium in ore samples with the recovery of 93%.
