液-液分离是溶剂萃取法中一个不可缺少的过程。 萃取法作为一个单元操作,在石油化工、食品加工、抗菌素处理、环境保护、有机合成、分析化学等众多方面有广泛的应用。在金属分离方面,首先在核燃料工业、稀有冶金工业上得到应用。铀就是在工业上第一个使用萃取法提取和纯化的金属。然而,近十几年的发 Liquid-liquid separation is an indispensable process in solvent extraction. Extraction method as a unit operation, in the petrochemical industry, food processing, antibiotic treatment, environmental protection, organic synthesis, analytical chemistry and many other aspects of a wide range of applications. In the metal separation, the first in the nuclear fuel industry, rare metallurgical industry has been applied. Uranium is the first metal in the industry to be extracted and purified by extraction. However, nearly ten years of hair
