【摘要】 本文研究了碱土金属和部份过渡元素在D-751大孔螯合树上的离子交换平衡,确了该种定树脂对各金属离子的选择性序列。在此基础上研究了金属离子在D-751树脂柱上的前列和洗脱色谱行为。采用不连续酸度梯度洗脱可以获得多元混合物的完全分离。更多还原

【Abstract】 This paper investigated the equilibrium of alkali-earth metal and some transition metal ions on D-751 chelating resin. Selectivity of the resin for the me tal ions was established Based on these data it covers as well the chromatography of the metal ions on column filled with D-751 resin by the frontal and the elution method. A conclusion is drown that multicomponent mixture can completely be separated by stepwise PH changes during the elution.更多还原
