摘　　要：报道了基于乙酰丙酮二缩乙二胺铜(Ⅱ)(Cu(Ⅱ) BAEDI)为载体的溶剂聚合膜阴离子敏感电极,该电极对I-具有高的电位选择性能和灵敏度,且呈现反Hofmeis ter选择性行为。采用交流阻抗和光谱分析技术研究了电极的响应机理,并将电极用于加碘盐中碘含量的测定,结果令人满意。In this paper, anion-selective electrode based on bisacetylacetone-ethylene dimine copper(Ⅱ) metallic complex (Cu(Ⅱ)-BAEDI) as the neutral carrier is reported. The sensor exhibits a unique selectivity and high sensitivity toward iodide, which displays an anti-Hofmeister selectivity pattern. The electrode can be applied to food analysis and the result is in fair agreement with the result given by spectrophotometry.
