▎ 摘 要
A conductive carbon black-graphene (CCB-GR) modified glassy carbon electrode (CCB-GR/GCE) has been fabricated and used for determination of rutin. Transmission electron microscopy (TEM) results indicated that CCB-GR was successfully prepared. Cyclic voltammetry (CV) and differential pulse voltammetry (DPV) results showed that CCB-GR/GCE exhibited an excellent electrochemical performance. The sensing platform showed wide linear responses for rutin from 1x10(-9) to 1x10(-4) mol L-1 with a detection limit of 3.3x10(-10) mol L-1 (S/N = 3). The CCB-GR/GCE showed excellent sensitive with good stability toward the determination of rutin content in tablet.
