摘　　要：建立了过氧化聚吡咯(OPPy)和聚乙烯吡咯烷酮(PVP)修饰碳糊电极测定废水中苯酚的方法。优化了试验条件,苯酚的氧化峰电流在1.0×10-5mol/L^1.0×10-3mol/L之间线性关系良好,检出限为1.0×10-6mol/L。该电极制作简单,选择性好,测定灵敏度高,精密度与准确度均符合要求。A new method of a carbon paste electrode coated with Overoxidized Polypyrrole （OPPy） and Polyvinylpyrrolidone （PVP） has been developed for determination of phenol in wastewater. Optimized the test condition, the linear relation of oxidation peak current and the concentration of phenol is good and the range between 1.0 × 10 ^-5 mol/L to 1.0 × 10^ -3 mol/L. The detection limit is at 1.0 × 10^ -6 mol/L. The modified electrode is easily prepared and has high sensitivity and selectivity. The test result shows the accuracy and precision of the method meet the demand of the phenol determination.
