本文报告钙式树脂[含痕量钻(Ⅱ)]和氯化钙溶液,钻式树脂和氯化钙、氯化镁及氯化钡溶液的粒子扩散速率的测定。个别离子的迁移率对交换速率有影响,粒子扩散系数随平衡分数而改变。在Zerolit 225离子交换树脂上,钻(Ⅱ)和钙的粒子扩散系数依次为1.98×10-7和1.37×10-7厘米2·秒-1。

The rates of particle diffusion between calcium-form ion exchanger containing micro-component Co (Ⅱ) and calcium chloride solution, between cobalt-form ion exchanger and calcium chloride, magnesium chloride and barium chloride solutions and between calcium-form ion exchanger and cobalt chloride solution have been measured. It was found that the rate of ion exchange depends on the migration of individual ions and that the partitle diffusion coefficient changes with the fractional attainment of equilibrium.
