摘要
用溶剂萃取可以有效地进行碱土金属离子间的分离,从而能使产品纯度和原料利用率大幅度提高,根治污染。并可生产适合高技术领域要求的高纯产品。分别考察了二(2—乙基己基)磷酸、2—乙基己基磷酸2—乙基己基酯、二(2,4,4—三甲基戊基)膦酸的煤油体系对碱土金属离子的萃取行为。
Alkaline - earth elements can be effectively separated by using solvent extraction. The purity of the products and recovery can be dramatically increased, and the pollution from the process can be eliminated. The solvent extraction behaviors of di-(2- ethylhexyl)phosphoric acid, 2 - ethyl-hexyl phosphonic acid mono - 2 - ethylhexyl ester and di -(2, 4,4 -trimethylpentyl)phosphoric acid have been examined.
