Abstract
This review summarizes a potentiometric flow injection method for the determination of several redox species by using both a redox potential buffer solution consisting of a redox couple such as Fe(III)-Fe(II), Fe(CN)63--Fe(CN)64- and bromide-bromine, and a platinum electrode or a combined platinum-bromide ion selective electrode. The analytical principle and advantages of the proposed method are described and several examples of its application are demonstrated.
