Donoso,Latlmer,叶华利、谭政之、陈靖英等分别对镓在不同体系中的示波极谱行为进行了研究。这些方法的灵敏度尚不够高,选择性亦欠佳。在国内,铜铁试剂络合物吸附波法已成功地应用于测量钪等金属离子。我们发现在 pH≈4的乙酸-乙酸钠缓冲溶液中,镓亦能与铜铁试剂、二苯胍形成灵敏的吸附波,此法与本文完成后所见文献相比,选择性与灵敏度均较 Donoso, Latlmer, Ye Huali, Tan Zhengzhi, Chen Jingying et al. Studied the oscillopolarographic behaviors of gallium in different systems respectively. The sensitivity of these methods is not high enough, the selectivity is not good. In China, copper and iron reagent complex adsorption wave method has been successfully applied to the measurement of scandium and other metal ions. We found that gallium can also form sensitive adsorption wave with copper and iron reagent and diphenylguanidine in pH≈4 acetate-sodium acetate buffer solution. Compared with the literatures after the completion of this paper, the selectivity and sensitivity of gallium
