Summary:The process for separating Ge by liquid-liquid extraction features that 7-(2'-alkyl-1'-ene)-8-hydroxyquinoline as extractant is used to selectively extract Ge from the aqueous solution of sulfate or chloride. Its advantages include high extraction power, and the possibility to back-extract Ge from loading organic phase at room temp. by means of alkaline medium or to extract Ge from accompanying metals easily.
