Abstract
Silver ion can perturb the Belousov-Zhabotinskii (B-Z) oscillating chemical reaction. Therefore, the B-Z oscillating system was applied in the determination of silver ion by using a platinum wire as an indicator electrode in the potentiometric method. The amplitude of the potentiometric oscillation increased linearly in proportion to [Ag+] in the range of 9.42 × 10-6 M to 2.54 × 10-4 M, with a correlation coefficient of 0.999 under the optimum conditions. The obtained LOD (2 σ) was 8.85 × 10-6 M and the relative standard deviation (RSD) for five measurements of 1 × 10-4 M silver ion was 5%. The influence of some potentially interference was also investigated.
