【摘要】 将锑酸锌无机离子交换剂制成离子交换纸,对47种金属离子的层析行为进行了研究。选用二甲亚砜(DMSO)+硝酸,DMSO+水及硝酸水溶液为展开剂,探讨了金属离子的R_f值与DMSO,硝酸浓度、离子势等之间的规律性。实验表明,选择合适的层析条件,许多离子对或组的分离是成功的。更多还原

【Abstract】 The chromatographic behavior of 47 metal ions was investigated on plain and ZnSb papers in dimethylsulfoxide-nitric acid and aqueous nitric acid systems. The relations between R f values of some metal ions and DMSO, concentration of nitric acid, ion potential, screening-loss parameters of ions were discussed. The results showed that a lot of ion-couples or groups were separated under proper conditions.更多还原
