dc.description.abstract制备FeCl3改性钠基蒙脱土修饰电极,循环伏安法研究多菌灵在该电极上的电化学行为,以及溶液pH值、扫描速率、修饰剂用量等影响因素,并测定电极反应的部分动力学参数.结果表明,该电极过程由扩散步骤控制,转移电子数n=2,电极的活化表面积A=0.027 cm2,扩散系数D=5.115×10-6cm2/s.在优化测定条件下发现,峰电流的一阶导数值与多菌灵浓度在2.00×10-5~8.00×10-4mol/L范围内呈良好的线性关系.ip′=-8.045×10-7-0.0237c,相关系数R=-0.9965,检出限为2.41×10-6mol/L.线性扫描伏安法测得BCM试样的回收率为95.73%~104.0%.zh_CN
dc.description.abstractThe FeCl3 modified clay electrode was made.The electrochemical behavior of carbendazim(BCM) on the modified electrode was studied by cyclic voltammetry.The impacts of pH,scan rate and dosages of modifier were discussed and the important kinetic parameters of the electrochemical process were determined.The results indicated that the process was controlled by diffusion.The effective area of FeMM-CMC/GCE(A)=0.027 cm2,the transfer electron numbers(n)=2 and the diffusion coefficient(D)=5.115×10-6cm2/s.Under the optimized conditions,a good linearity was found between the first order derivative of peak current and concentration of BCM in the range of 2.00×10-5~8.00×10-4mol/L,with i′p=-8.045×10-7-0.0237c,correlation coefficient R=-0.9965,and the detect limitation of 2.41×10-6 mol/L.The recovery of BCM was detected with linear sweep voltammetry(LSV) were between 95.73% and 104.0%.zh_CN
