阳离子离子交换的色谱行为的一般原则的研究已有论述,然而用于理论计算的关系式及原则似未见报道,我们研究了一些阳离子在硝酸、盐酸、硫酸及高氯酸中的离子交换平衡常数K_x与离子势(z/r)之间的定量关系,并用数学关系式来描述。用这种定量关系计算出的阳离子的选择性顺序及分配比与经典理论和实验结果是基本一致的。
The general principles for the chromatographic behavior of cation-exchange have been discussed. However, the relationships and principles used for theoretical calculations have not been reported. We studied the ion exchange equilibrium of some of the cations in nitric acid, hydrochloric acid, sulfuric acid and perchloric acid The quantitative relationship between the constant K_x and the ion potential (z / r) is described by a mathematical relation. The selectivity order and distribution ratio of cations calculated by this quantitative relationship are basically the same as the classical theory and experimental results.
