1Determination of Omethoateby Cathodically SweepingOscillopolarography显示文摘Determination of omethoate by cathodically sweeping oscillopolarography is described. The product of the alkaline hydrolysis exhibited a sensitive second derivative wave at-0.50 V(vs. SCE) in a 1. 0×10-5mol/L sodium dodecylbenzene sulfonate (SDBS) + 0. 1 mol/L HAc-NaAc (pH 4. 0) buffer. The peak current was linearly proportional to the concentration of omethoate in the range from 6. 4 ×10-7 to 5. 1 ×10-5mol/L. The detection limit is 2. 0 ×10-7mol/L with the relative standard derivation (RSD) of 3. 5 %. The hydrolysis procedure and the electrode reaction were studied by voltammetry.Wang Yu Sun Yuansi Huang Junhua Zhang Wuming Zhou Xingyao(College of Chemistry, Wuhan University, Wuhan 430072,China) 1998Wuhan University Journal of Natural Sciences1998,3,4:2
