摘　　要：应用溶剂热法分别合成了Cu-MOF与MWCNTs,然后制备Cu-MOF/MWCNTs复合材料。将制备得到的Cu-MOF/MWCNTs复合材料滴涂到电极表面,采用循环伏安法(CV)探究对特辛基苯酚(POP)在Cu-MOF/MWCNTs修饰电极上的电化学行为。实验结果表明,用Cu-MOF/MWCNTs修饰的电极对POP有明显的电催化活性,POP在该电极上的反应受吸附控制,其氧化峰电流与POP的浓度在1~50μmol/L区间内有良好的线性关系,ΔI=-7.96582-0.89821C(R2=0.9971),方法检出限(S/N=3)为9.51×10^(-7)mol/L。用该分析方法检测一次性聚苯乙烯塑料餐盒的样品,POP加标平均回收率为98.9%~100.4%,测定值的相对标准偏差(n=6)为3.02%~4.00%。Cu-MOF and MWCNTs were synthesized by solvothermal method,and then Cu-MOF/MWCNTs composites were prepared,which was dropped onto the electrode surface,and the electrochemical behavior of POP on the Cu-MOF/MWCNTs modified electrode was studied by cyclic voltammetry(CV).Experimental results showed that the electrode modified with Cu-MOF/MWCNTs had obvious electrocatalytic activity for p-(Tert-octyl)phenol(POP).The reaction of POP on the electrode was controlled by adsorption.The oxidation peak current had a good linear relationship with the concentration of POP in the range of 1-50μmol/L with a detection limit of 9.51×10^(-7) mol/L(S/N=3),ΔI=-7.96582-0.89821 C(R2=0.9971).Using this analytical method to detect samples of disposable polystyrene plastic lunch boxes,the average recovery of POP was 98.9%-100.4%,and the relative standard deviation of the measured values(n=6)was 3.02%-4.00%.
