文摘The possibility and optimal conditions have been studied for coulometric titration of Tl（Ⅲ） with electrogenerated ferrocyanide ion to be used as titrant. It has certain advantages over the directly potentiometric titration. It was shown that the reaction of Tl（Ⅲ） with ferrocyanide ion produces Tl5K[Fe（CN）6]4↓. The weight W of Tl is given by the following expression:
