| Abstract: | 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. |
