催化极谱因具有比经典极谱高得多的灵敏度,且不受仪器种类限制,已日益引起人们的重视。有关极谱催化电流的理论和应用已有系统的研究和叙述。一般说来,“催化极谱”是研究电极过程中的催化效应产生的迭加在扩散电流上的附加电流(即催化电流)的特性及应用,由于它比原有扩散电流大很多倍(甚至可提高几个数量级),因而它在分析化学中的应用就显得很有意义。
Because of its much higher sensitivity than classical polarography, and not limited by the type of instrument, the catalytic polarographic has drawn more and more attention. The theory and application of polarographic catalytic current have been systematically studied and described. In general, “catalytic polarography” is to study the characteristics and applications of the additional current (ie, catalytic current) superimposed on the diffusion current caused by the catalytic effect in the electrode process. Because it is many times larger than the original diffusion current Can increase several orders of magnitude), so its application in analytical chemistry makes sense.
