Different substances were researched to modify glassy carbon electrode to make pH sensors.By means of potential titration,it was found that the electrode first modified with polyaniline and then with cobalt-cobalt oxide could had a good pH response.And it could be applied to the titration of real samples in place of glass electrode.Moreover,the best polymerization conditions were cyclic voltammetry scan 10 cycles at a concentration of 0.1 mol/L polyaniline in hydrochloride solution(1 mol/L) under the potential between-0.2 V to 1.0 V and cyclic voltammetry scan 5 cycles at a concentration of 2.0×10^-4 mol/L cobalt in PBS solution(pH=7.5) under the potential between-1.2 V to 1.2 V.This electrode could have a response slope of-61.60 mV/pH,and the pH response range was from 0.5 to 13.
