    • Method for selectively extracting germanium from an aqueous acid solution containing, in addition to germanium, at least another metal selected from the group comprising cadmium, zinc, cobalt, iron, arsenic, aluminium, gallium and nickel. This method comprises the following steps: - extraction of germanium from said aqueous solution by contacting said solution with an organic medium which contains a diluent and an extractant, said diluent being immiscible with said aqueous solution. - an elution of germanium from said organic phase by contacting said phase with an aqueous medium, said elution step forming an aqueous phase containing most of the germanium of said aqueous solution and an organic phase containing said diluent and said extractant.
    • 从含有除了锗之外的至少另一种选自包含镉,锌,钴,铁,砷,铝,镓和镍的金属的酸性水溶液中选择性提取锗的方法。 该方法包括以下步骤: - 通过使所述溶液与含有稀释剂和萃取剂的有机介质接触,从所述水溶液中提取锗,所述稀释剂与所述水溶液不混溶。 - 通过使所述相与水性介质接触,从所述有机相中洗脱锗,所述洗脱步骤形成含有大部分所述水溶液的锗的水相和含有所述稀释剂和所述萃取剂的有机相。
