钼的催化波原有三种:即Mo(Ⅵ)—H_2O_2(硫酸或磷酸緩冲溶液)、Mo(Ⅳ)—HClO_4和Mo(Ⅲ)—HNO_3;由于催化电流远大于钼的正常扩散电流,可利用它来測定微量的钼。我們在研究钛的催化波时发現钼与氯酸鉀有双峯的催化电流。1962年邓家祺和汪乃兴在硫酸酒石酸溶液中得到Mo—KClO_3单峯的催化波。最近Kolthoff和Hodara报导了钼对氯酸鈉、高氯酸鈉和硝酸鈉还原的催化波。所以到目前为止钼的催化波共有四种。我們研究了这四种催化波的性质、化学反应、
The catalytic wave of molybdenum has three kinds: Mo (Ⅵ) -H_2O_2 (sulfuric acid or phosphoric acid buffer solution), Mo (Ⅳ) -HClO_4 and Mo (Ⅲ) -HNO_3. Because the catalytic current is much larger than the normal diffusion current of molybdenum, Use it to determine trace amounts of molybdenum. When we studied the titanium catalytic wave we found that the molybdenum and potassium chlorate have a bimodal catalytic current. In 1962, Deng Jiaqi and Wang Naixing got the catalytic wave of Mo-KClO_3 single peak in tartaric acid solution. Recently Kolthoff and Hodara reported the catalytic wave of molybdenum reduction of sodium chlorate, sodium perchlorate and sodium nitrate. So far, there are four catalytic waves of molybdenum. We studied the four catalytic wave properties, chemical reactions,
