摘　　要：文章对采用氢氧化镁吸附和树脂吸附从老卤中除硼进行了研究。实验结果表明:氢氧化镁吸附除硼的效果较差,而除硼树脂D403对老卤的除硼效率较高,当净化卤水的体积为树脂体积的4倍时,脱硼率可达到80%以上。采用较高浓度的盐酸洗脱,不仅洗脱效果好,而且洗脱液中硼含量高,镁含量低,因而有利于从中回收硼。In this paper,the elimination of boron from the bittern by the adsorption with magnesium hydroxide and the resin was studied.The results showed that the efficiency of elimination of boron by the adsorption with magnesium hydroxide was quite poor,but the efficiency with the resin D403 was very high,where the rate of eliminating boron could reach over 80% when the volume of the bittern purified was fourfold the volume of resin.The resin adsorpted by boron could be eluted efficiently with higher concentration of hydrochloric acid,and the content of boron in the elution was higher,but the content of magnesium was very lower,which was advantageous to recover boron.
