化学发光分析是近年来开展起来的一种高灵敏度的分析方法,将其与催化动力学分析法结合不仅为催化动力学分析法提供了一类新型灵敏的指示反应,对扩大化学发光分析的应用范围也具有一定意义。我们曾试用H_2O_2—S_2O_3~(2-)—V(V)体系的催化动力学反应与H_2O_2—Fe(CN)_8(6-)—Luminol的化学发光反应偶合对痕量钒进行测定,获得了满意的结果,本文根据C1O_3~-与I~-离子的反应可被V(V)催化,产物I_2分子又可氧化Luminol产生化学发光的性质,根据光信号的强度指示反应中催化剂的含量,
Chemiluminescence analysis is a highly sensitive analytical method developed in recent years. Combined with catalytic kinetic analysis, chemiluminescence analysis not only provides a new sensitive indicator reaction for catalytic kinetic analysis, but also expands the application of chemiluminescence analysis Range also has some significance. We have tried to measure the trace vanadium by coupling the catalytic kinetic reaction of H_2O_2-S_2O_ (2 -) - V (V) with the chemiluminescence reaction of H_2O_2-Fe (CN) _8 (6 -) - Luminol. Satisfactory results, this paper according to the reaction of C1O_3 ~ - with I ~ - ions can be V (V) catalysis, the product I_2 molecules can be oxidized Luminol chemiluminescence properties, according to the light signal intensity indicates the reaction catalyst content,
