催化动力分析法,由于它的灵敏度高和选择性好,副反应影响小,在痕量分析中较为重要;亦用于动力学及反应机理的研究,因而发展迅速,可测定元素约50种。其中催化电位法,近来土耳其的Altinata、希腊的Hadjiioannou、日本的片冈正光和我国的一些学者在这方面作了一些工作。为了克服电位法灵敏度不高以及测定的离子尚没有相应的离子选择电极的困难,起用催化电位法是重要的途径之一。 Due to its high sensitivity and selectivity, catalytic kinetic analysis is more important in trace analysis because of its high sensitivity and selectivity. It is also used in the study of kinetics and reaction mechanism, and has been rapidly developed. About 50 kinds of elements can be determined. Among them, the catalytic potentiometry, Altinata in Turkey recently, Hadjiioannou in Greece, Masaaki Kataoka in Japan and some scholars in our country have done some work in this respect. In order to overcome the potential law is not high sensitivity and the determination of ion does not yet have the corresponding ion-selective electrode difficulties, the use of catalytic potential method is one of the important ways.
