Abstract
In the article possibility of water solution LiOH tertiary treatment from chlorine anions after electrolysis is viewed. Analyzing the existing purification methods, it is proposed to use the purification of lithium hydroxide in an ion exchange column. A mathematical model and a computational algorithm for ion exchange column having stationary and moving anionite layers AВ-17-08 in ОН-form are given. Relationships of the main parameters such as working cycle period, usage ratio of ionite exchange volume and specific ratio of solution being purified per 1 kg ionite for standard column have been received. The curves of the chlorine anions density in ionite depending on its layer height in the solution being purified in the middle and at the end of the working cycle period are given. In the article recommendations on prevention of ionite granules abrasion during the operation in ion exchange columns are given.
