中文摘要	利用层接层自组装法(Layer-by-Layer Self-Assembly,LbL),制备出有序且稳定的多金属氧酸盐K17[Ce(P2Mo17O61)2]的多层膜修饰电极。电极对溶液中的碘离子具有良好的电催化氧化作用,已成功地应用于流动注射安培检测法对海带中碘含量的检测,结果令人满意。; The electrode modified by multilayer films of polyoxometalate(POM) K17[Ce(P2Mo17O61)2] and polyelectrolyte by means of layer-by-layer assembly was prepared and investigated. The stable multilayer films were assembled by alternate adsorption of negatively charged POM and positively charged polyelectrolyte from their aqueous dispersions. The proposed novel electrode exhibited a good electrocatalytic oxidation on I-anions in solution. Based on this, flow injection amperometry was proposed for the determination of iodide. By the flow injection amperometry(FIA), there existed a good linear relationship between the concentration of iodide and the response current in a range of 1×10-5 mol/L and 1×10-3 mol/L, and the detection limit was 5×10-5 mol/L. The method has been successfully applied to the determination of iodide in dry edible seaweed. The concentrations of iodide measured by this method are in good agreement with those obtained by spectrophotometric method.; 【作者单位】集美大学生物工程学院；泉州师范学院化学与生命科学学院；【作者英文名】WANG Li a, WANG Fang b, DONG Le b, CAI Hui-Nong a(aSchool of Biotechnology,Jimei University,Xiamen 361021;bChemistry and Life Science School,Quanzhou Teachers College,Quanzhou)
