摘  要:
钨丝聚苯胺修饰的为工作电极,Ag/AgCl为参比电极所构成的pH传感器,在pH2~12范围内呈现Nernst响应,时间小于1min。该传感器从河鲫鱼由活体到一步步腐败的过程中其pH值的变化得到了很好的分析。

摘  要:
A tungsten electrode modified with polyaniline was prepared as working electrode. Ag/AgCl redox system was used as reference electrode. The sensor showed a Nernst response in the pH range of 2~12 with a response time less than 1 min. The sensor has been successfully employed to determine pH in the crucian from both the live fish to the putrefied fish.
