| 摘 要： | 本文确认了从A、B和C三个矿点的矿坑水回收铀过程中201×7树脂中毒主要是由腐植酸(盐)引起的;中毒的主要特征是离子交换速度降低,而对其交换容量则影响不大。通过对树脂中毒机理的探讨,提出了中毒模型。

| Abstract: | The strong- ase ion exchange resin 201 x 7 is used to recover uranium from the nearly neutral and weak alkaline mine water of three mines A, B -and c. The poisoning of resin is found to be very serious. The retails of investigation by using infrared spectometry and others show that the poisoning of the resin originates from the humic acid (salt). The de creasing of speed of ion exchange is the main feature, but there is no significant effect on ion exchange capacity of the resin. The mechanism of the poisoning is also explored and the model of poisoning is given as follows, the humie acid (salt) stops up the vacant sites of the resin as a sponge and occupies a lot of them. |
