摘要
本文叙述了聚对甲苯胺修饰电极的制备及其电化学响应特性。在ｐＨ２～１３范围内电极电位与ｐＨ有良好的线性关系，电极响应快，导电性能良好，抗干扰性能强，不受氧化还原物质影响。用于测定饮料、湖水的ｐＨ值，结果与玻璃电极测定值基本相符。
his paper states the prepatation andelectrochemical response characteristics of the poly( p-methylaniline)film modified Pt electrode as a potentialsensor,A good linear relationship between themodified electrode potential and pH is obtained in therange of pH2～13.The medified electrede has theadvantages of good reproductivity and stability,highdectrical condticibility,short response time,and it canbe used continuously for about a month.Redoxmaterials and some coexisting ions do not interferewith the determination of pH.The pH values of drinksand lake Water determined by this modified electrodeare consistent with those determined by the glassdectrde.
