研究了CL -5 2 0 9萃淋树脂吸附钍的性能和机理 ,并用减压微色谱柱考察了相关离子的萃取色谱行为。选择了分离钍的最佳条件 ,用于矿样中微量钍的分离和测定 ,取得了满意结果
The performance and mechanism of adsorption of thorium on CL-5290 extraction resin were studied. The extraction chromatographic behavior of related ions was investigated by vacuum microchromatography. The optimal conditions for the separation of thorium have been selected for the separation and determination of trace amounts of thorium in the ore samples with satisfactory results
