用电化学方法聚合分子筛孔道内的苯胺，以聚苯胺分子筛修饰电极为模型研究分子筛修饰电极的内电子传输机理．ＮａＹ分子筛的离子交换点位被苯胺修饰后，通过电聚合制得聚苯胺分子筛修饰电极（Ｐａｎ＋Ｙ－ＺＭＥ），该电极通过聚苯胺链自身的电子跳跃来实现电子传输，且只有通过阴极富集后对溶液中Ｃｄ２＋才有响应，并能用于测定抗坏血酸
The aniline in molecular sieves was electrochemically polymerized. The polyaniline molecular sieve modified electrode was used as a model to study the internal electron transport mechanism of molecular sieve modified electrodes. After the anion exchange sites of NaY zeolite were modified by aniline, polyaniline molecular sieve modified electrode (Pan + Y-ZME) was prepared by electropolymerization. The electrode was electronically transferred by the electron-hopping of the polyaniline chain, and only after cathodic enrichment The solution of Cd2 + only response, and can be used to determine ascorbic acid
