Abstract: A new method named double electrolytic cell positive feedback oscillographic chronopotentiometry was presented in this paper, and its repeatability was studied.The minimum concentration yielding a measurable incision was determined.The major factors affecting the results of positive feedback were also discussed.The experimental results show that the sensitivity of the new method is 1-5 times as high as that of classical method.Therefore, the new method is very useful in microtitration, and it has an important significance to enhance sensitivity of reprocal oscillographic chronopotentiometry as well as other methods based on (dE/dt)-Ecurves.

Key words: Positive feedback oscillographic chronopotentiometry, Double electrolytic cell, Incision
