摘要
将聚苯胺修饰的钨丝电极为工作电极，Ag/AgCl电极为参比电极构成针型pH传感器。该传感器在pH2-12范围内呈现Nernst响应，响应时间小于1min。该传感器成功地应用于河鲫鱼由活体到腐败过程中pH值的变化测定。
A tungsten elctrode modified with polyaniline was prepared as work electrode.Ag/AgCl redox system was used as reference electrode.The sensor showed a Nernst response in the pH range of 2-12 and a response time of less than 1min.The sensor has been successfully employed to determine pH of crucian from the live fish to the putrefied fish.
