A sensitive peak current of p nitroacetophenone can be obtained in the solution of 0.025 mol·L -1 ethylene diamine 0.010 mol·L -1 EDTA.The peak potential is about -0.35 V(vs.SCE).The concentration of p nitroacetophenone is linear with peak current in the range of 3.00×10 -8 mol·L -1 to 1.00×10 -4 mol·L -1 .The limit of detection for the determination of p nitroacetophenone is 3.00×10 -8 mol·L -1 . This method can be used determination of p nitroacetophenone in the wastewater from chloromycetin factory and satisfied results have been obtained.
