摘要
拟定了测定金属铝中微量镓的新方法。以乙酸丁酯萃取镓 ,并用水反萃取 ,在乙酸—乙酸铵—铍试剂Ⅲ—抗坏血酸体系中 ,测定了金属铝中 0 0 0 0x %～ 0 0x %镓 。
A new method for the determination of trace Ga in metallic aluminium was developed In HAc-NH 4Ac-beryllon Ⅲ-ascorbic acid system,the range of 0 000x%-0 0x% for Ga in metallic aluminium has been determined by oscillopolarography after extraction with CH 3COO(CH 2) 3CH 3 and back extraction with water,and the results were satisfactory
