从含有Zn、As、Cd、Sb、In、Cu、Fe(Ⅱ)等一个或多个元素的酸性溶液中分离锗的方法,是用一种含α-羟基肟及至少一种烷基硫酸的有机相作萃取剂,以烃作稀释刘进行液-液萃取。 本工艺使用一种多级逆流革取器。α-羟肟是5,8-二乙基-7-羟基-6-十二烷酮,烷基硫酸最好是单-2-乙基已基硫酸和双-2-乙基已基硫酸。羟肟与单-2-乙基己基硫酸的体积比为7:1到7:5或17:4到14:5;羟肟与单-2-乙基己基硫酸和双-2-乙基已
A method of separating germanium from an acidic solution containing one or more elements of Zn, As, Cd, Sb, In, Cu, Fe (II) and the like is to use a solution of α-hydroxyoxime and at least one alkylsulfuric acid Organic extractant to hydrocarbon as a diluent Liu liquid - liquid extraction. The process uses a multi-stage countercurrent picker. The? -hydroxime is 5,8-diethyl-7-hydroxy-6-dodecanone, and the alkylsulfuric acid is preferably mono-2-ethylhexylsulfuric acid and bis-2-ethylhexylsulfuric acid. The ratio by volume of hydroxyoxime to mono-2-ethylhexylsulfonic acid is from 7: 1 to 7: 5 or from 17: 4 to 14: 5; the ratio of hydroxime to mono-2-ethylhexylsulfate and bis-
