| 摘 要： | 制备了多壁碳纳米管-聚茜素红膜(MWNT-PAR)修饰电极,用循环伏安法和线性扫描伏安法、计时电量法等研究多菌灵在修饰电极上的电化学行为.结果表明,多菌灵在MWNT-PAR修饰电极上是扩散控制的不可逆电氧化过程.实验测定了部分电极过程参数,并发现多菌灵氧化峰电流的一阶导数值与其浓度在5.0×10~(-6)～1.0×10~(-4) mol/L范围内呈线性关系,回归方程为:I_p ′(A)=-3.112×10~(-6)-1.198c(mol/L),R=-0.9953,其检出限为2.0×10~(-7) mol/L,回收率为99.0%～105.6%.

| Abstract: | Multiwalled carbon nanotubes-Polymeric alizarin film modified electrode(MWNT-PAR) was prepared,and the electrochemical behavior of carbendazim on the modified electrode was studied with cyclic voltammetry,linear sweep voltammetry and chronopotentiometry.The electrical oxidation of carbendazim on MWNT-PAR electrode was irreversible and was controlled by diffusion.Some parameters of the electrochemical process were evaluated and good linear relationship between the 1st order derivative of peak current and its... |
