| Abstract: | A new m ethod ofa carbon paste electrode coated with Overoxidized Polypyrrole(OPPy) and Polyvinylpyrrolidone(PVP) hasbeen developed fordeterm ination ofphenolin wastewater. Optimized thetest condition, thelinearrelation ofoxidation peak currentandthe concentrationofphenolisgood andtherangebetween1.0×10 - 5 mol/L to1.0×10 - 3 mol/L. The detectionlimitisat1.0×10 - 6 mol/L. The modified electrodeiseasily prepared and hashighsensitivityandselectivity. Thetestresultshowsthe accuracyand precision ofthe methodmeetthe demand ofthephenoldetermination. |
