【摘要】 在0.06mol·L^-1NH₄OAc底液中,铟与4-（2-噻唑偶氮）-间苯二酚（TAR）形成的络合物产生一灵敏还原吸附峰,可用于单扫描示波极谱法测定痕量铟。铟浓度在1×10^-8～1×10^-6mol·L^-1范围内与峰电流呈线性关系。加入少量十二烷基磺酸钠,灵敏度提高,检出下限为5×10^-9mol·L^-1。该法应用于测定矿石中痕量铟,结果令人满意,用多种电化学手段对络合物的电化学性质进行了研究。更多还原

【Abstract】 In 0. 06mol ·L^-1 NH₄OAc buffer solution,a sensitive adsorptive wave of the complex of indium with TAR is observed by using linear sweep voltammetry. The peak height of the adsorptive wave is directly proportional to the concentration of indium in the range 1 X 10^-8l × 10^-6mol ·L^-1. This method has been applied satisfactorily to the determination of traces of indium in ores. The electrochemical behaviour of the complex of indium with TAR was investigated using differential electrochemical techniques.更多还原
