一般极谱分析的灵敏度为10~(-4)M,而利用催化电流则可测量10~(-6)”—10~(-7)M甚至10~(-8)M。文献上已应用的有铁、钼、钨、铀、铼、铅、铂、砷、和锑等。另外如铌和锆也研究了它们的催化波,但还少见应用。近年来捷克的科学家们深入研究了极谱动力学,对其中催化电流从理论上加以探讨,从而求得Fe~(++)—H_2O_2,Fe~(++)—NH_2OH、U~(+++)—NO_3~-、Ti~(+++)—ClO_3~-等催化反应的速率常数。产生以上各种催化波的原因是不尽相同的。这里我们先介绍化学反应平行于电极反应的一种催化波——钛的极谱催化波。
The sensitivity of general polarographic analysis is 10 ~ (-4) M, while the catalytic current can measure 10 ~ (-6) "-10 ~ (-7) M or even 10 ~ (-8) M. There are iron, molybdenum, tungsten, uranium, rhenium, lead, platinum, arsenic, and antimony etc .. In addition, such as niobium and zirconium have also studied their catalytic wave, but still rare applications. In recent years, Czech scientists have studied the pole In this paper, the catalytic kinetics was studied theoretically, and the catalytic activity of Fe ~ (++) - H_2O_2, Fe ~ (++) - NH_2OH, U ~ (+++) - NO_3 ~ +++) - ClO 3 ~ -, etc. The reasons for the above catalytic reactions are not the same. Here we first introduce the catalytic reaction of a chemical reaction parallel to the electrode reaction - titanium polarographic Catalytic wave.
