摘　　要：本文把流动注射与在线氧化生成挥发性碘技术结合起来，不仅可以提高测定的灵敏度，而且可以减少氯化钠对测定的干扰。检出限达0.04mg／L。本法简便快速，易于操作，灵敏度高。The techniques of flow injection analysis and on-line oxidation of iodide were con bined and studied in this paper. A new analytical method of determining iodine was estab lished, in which not only the sensitivity can be enhanced a hundred times , but also the ad sorption of iodine molecules on the system and the interferences of NaCl were eliminited.The detection limit is 0. 04 mg/L. The method is simple, fast and easy to operate.
