在ＨＣｌ－Ｋｃｌ和聚乙烯醇介质中，用单扫示波极谱法得到了两个灵敏的镓（Ⅲ）、铟（Ⅲ）和对氨基苯基荧光酮配合物的吸附波。两波的峰电位依次为－１．０Ｖ和－０．６５Ｖ（ｖｓ．ＳＣＥ），线性范围：镓（Ⅲ）０．００８～０．６μｇ／ｍｌ，而铟（Ⅲ）０．００１～０．３μｇ／ｍｌ。用于矿石中镓和铟的直接测定，结果满意。文中还探讨了有关反应机理。
The adsorption waveforms of two sensitive complexes of gallium (Ⅲ), indium (Ⅲ) and p-aminophenylfluorone were obtained by single sweep oscillopolarography in HCl-KCl and polyvinyl alcohol media. The peak potentials of the two waves were -1.0V and -0.65V (vs.SCE), respectively. The linear range was 0.008-0.6μg / ml for gallium (Ⅲ) and 0.001-0.0% for indium (Ⅲ). 3 μg / ml. For the direct determination of gallium and indium ore, the results are satisfactory. The paper also discusses the reaction mechanism.
