关于排代色层中稳定区段的两相组成,前人曾作过研究,提出了二些计算公式。由于其中引入了很多高温高压下难于获得的常数,所以不适用于高压离子交换法。因此我们在研究排代离子浓度与两相组成关系的基础上,找到了用排代离子浓度计算稳定区段两相组成的经验式。 实验方法同上篇报告,pH测定用上海产的PH-S-2型酸度计;铵的测定用Kjeldahl法。
As for the two-phase composition of the stable section in the displacement color layer, some previous studies have been made and two calculation formulas have been proposed. Due to the introduction of a lot of high temperature and pressure difficult to obtain the constant, it is not suitable for high pressure ion exchange method. Therefore, based on the study of the relationship between the displacement ion concentration and the two-phase composition, we find the empirical formula for calculating the two-phase composition of the stable zone by using the displacement ion concentration. Experimental methods As reported in the previous paragraph, pH measurement using Shanghai-based PH-S-2 type acidimeter; Determination of ammonium Kjeldahl method.
