Abstract
The chemical oscillation chronoamperometry was firstly set up as a new analytical method. The electrocatalysis of bromide with various poly(3-alkylthiophene) modified electrodes was studied and compared. This modified electrode was successfully applied to the chemical oscillation system 'aniline-sulfuric acid-potassium bromate' for chronoaperometric study. It was found that the logarithm of the oscillation period has a linear relationship with the concentration of aniline (r = 0. 9985). This method was applied to the determination of aniline in waste water with satisfactory results.
