摘要
通过考察不同温度下,硫酸水溶液中硫酸含量对硼酸溶解度的影响规律,提出冷却—酸化耦合提纯硼酸方法,为硼酸的分离提纯提供新思路。结果表明,通过调控溶液中硫酸加入量及冷却终止温度,可实现硼酸纯度的提高。
By investigating the influence law of sulfuric acid content in solution on the solu⁃bility of boric acid at different temperatures,an acidification-cooling coupled purification method for boric acid was proposed.This study can provide a new idea for the separation and purification of boric acid.The results show that the purity of boric acid can be improved by regulating the addition amount of sulfuric acid,the cooling termination temperature.
