Abstract: The equation of the pulse polarographic curve controlled by diffusion and a followed chemical reaction is derived in this paper.Tests were carried out to verify the theory by using the oxidation of cadmium amalgam in KNO3, HOAc-NaOAc, EDTA (or NTA) solution. The results obtained are in good agreement with the theoretical conclusion.The K,k1k2values determined agree with those obtained by other polarographic methods found in literatures.

Key words: Pulse polarography, Followed chemical reaction
