Abstract: A very simple and reliable electroanalytical method for the determination of aluminum in drinking waters by a.c. oscillopolarography using solochrome violet RS is described in this paper. In the buffer solution of 0.1 mol dm-3 NaAc-0.5 mol dm-3 KCI (pH 5.2) containing 7 x 10-4 mol dm-3 SVRS, a sensitive incision due to the redox reaction of Al-SVRS complex adsorption wave on the Hg-film electrode was observed on the dE/dt - E oscillogram. The incision depth was linearly proportional to the Al concentration in the range of 5 x 10-7 -6 x 10-5 mol dm-3 and was used to determine Al quantitatively. The experimental conditions were optimized. No serious interference was found. The detection limit of this method was 2 x 10-7 mol dm-3 and the relative standard deviation was 2.2 % for 5 x 10-5 mol dm-3 Al (n = 10). This method was successfully applied to the analysis of Al in real water samples and the results obtained by the proposed method were found to be in good agreement with the results obtained by the ICP-AES method.
