Gallium is efficiently extracted from strongly basic solutions containing aluminates by extractants having the tris-and/or tetrakis(2-hydroxybenzyl)-1,2-diaminoethane chemical moiety. The diaminoethane derivative may be used together with a hydrocarbyl 8-hydroxyquinoline and/or with a tertiary carboxylic acid.
具有三和/或四(2-羟基苄基)-1,2-二氨基乙烷化学分子的萃取剂可从含有铝酸盐的强碱性溶液中有效地萃取镓。 二氨基乙烷衍生物可与烃基 8-羟基喹啉和/或与叔羧酸一起使用。
