摘要：

A novel strategy for the sensitive determination of sulfonamide using glassy carbon electrode(GCE) modified by Fe3O4/functionalized Graphene (Gr/Fe3O4) was successfully developed in this work. The fabricated Gr/Fe3O4/GCE sensor demonstrated remarkable merits such as higher electrocatalytic activity, higher sensitivity and lower detection limit. Under optimized conditions, the modified electrode achieved a linear range of 5x10(-7) similar to 1.1x10(-4) mol/L with a detection limit of 5.0x10(-8) mol/L. The calibration curve could be expressed by the equation i(pa)(10(-6)A) = 1.356x10(-4) c (10(-5) mol/L)+0.898 with a linear coefficient of 0.994. The recovery rate was in the range of 88.5% similar to 104.0%, indicating the enormous potential and prospects of this method.
