用2-乙基已醇从东台吉乃尔湖酸化提硼母液中回收硼

Recovery of Boron from Boron Mother Liquid of Dong Taijinaier Lake With 2-ethyl Hexanol by Acidation Method

本文以东台吉乃尔湖酸化提硼母液为原料，研究了以２－乙基已醇磺化煤油体系对该类含高氯化镁卤水中硼的萃取，结果表明，在酸性条件下萃取，中性下反萃取，硼酸的萃取率与反萃取率均达９９％以上，并确定了最佳工艺参数。

In this Paper,it is studied that recovery boron from the higher MgCl 2 concentration brine by extraction of 2-ethyl-hexanol and sulfonated kerosine systems in tongtaijinaier lake. The conditions of extraction and reverse extraction are by the medium of acid and nature,respectively. The rates of extraction and reverse extraction are both more than 99%.The optimum data of this recovery process is also defined.
