Determination of p-aminophenol in water by an acetylferrocene modified carbon paste electrode

The electrochemical properties of p-aminophenol(PAP) on the acetylferrocene modified carbon paste electrode were characterized by linear sweep stripping voltammetry.The results showed that PAP was catalyzed on the modified electrode in phosphate buffer saline(pH 3.2).The calibration curve for PAP concentration was in the range from 7.0×10-7 to 3.0×10-5 mol/L with a detection limit of 1.0×10-7 mol/L(S/N=3).The method was applied to direct determination of PAP in water samples with satisfactory results.
