摘要：
A procedure is developed for the flow-injection determination of iodide using a modified silver electrode; it extends the analytical range of iodide by an order of magnitude as compared to potentiometric determination using an iodide-selective electrode with a polycrystalline membrane. The detection limit is 7 mu g/L. The procedure was used to determine iodide in natural mineral waters and model solutions. The throughput was 20-25 samples/h.
