虽然镓的极谱行为已经引起重视,但利用镓的螯合物性质来进行定量测量比较困难。在中性溶液中,波形由于离子的水解而扭曲,在酸性介质中,波又被H_3O~+的还原而难以辨认,在强碱性溶液中,镓酸盐不能被还原。因此,长期以来,极谱法测定镓很少应用,研究报导也少。 Latlmer和Копаиская曾进行过镓的有机化合物的极谱测定,他们所制定的在pH4.6±
Although the polarographic behavior of gallium has drawn much attention, it is difficult to make quantitative measurements using gallium chelate properties. In neutral solution, the waveform is distorted by the hydrolysis of ions. In acidic medium, the wave is hard to be recognized by the reduction of H_3O ~ +. In strong alkaline solution, the gallate can not be reduced. Therefore, for a long time, polarographic determination of gallium rarely used, research reports are few. Latlmer and Копаиская have carried out the polarographic determination of gallium organic compounds, they developed at pH 4.6 ±
