利用催化波的极谱分析,其灵敏度特别高。一般极谱分析可测至10~(-4)M 的浓度,若用催化波可提高二、三个至四、五个数量级。但到目前为止,催化波的机理不很清楚,因而在分析中的应用也不多。1943年以来捷克斯洛伐克学派系统地研究极谱动力波,给催化波中的一种类型提供了理论的根据。我们试就文献所载,初步把催化波分为三类:氢催化波,化学反应与电极反应平行的催化波,和其他催化波,并通过具体例子加以说明,也许对扩大催化波在极谱分析中的应用和深入研究其机理有些用处。
The use of catalytic wave polarographic analysis, its sensitivity is particularly high. General polarographic analysis can be measured to 10 ~ (-4) M concentration, if the catalytic wave can be increased by two, three to four, five orders of magnitude. But so far, the mechanism of catalytic wave is not very clear, so the application in the analysis is not much. The Czechoslovakian school systematically studied the polar dynamic wave since 1943, providing a theoretical basis for a type of catalytic wave. We try to document the literature, the catalytic wave is divided into three categories: catalytic hydrogen waves, chemical reactions and electrode reactions parallel to the catalytic wave, and other catalytic wave, and by specific examples to illustrate, perhaps to expand the catalytic wave in the polarographic Analysis of the application and in-depth study of the mechanism of some useful.
