英文摘要: Multi-walled carbon nanotubes (MWNTs) modified glassy carbon electrode (GCE) was simply and conveniently fabricated. The electrochemical properties of paracetamol (PCT) at the prepared modified electrode were investigated by cyclic voltammetry (CV). Based on this, an ultrasensitive and rapid electrochemical method was developed for the determination of PCT. The result indicated that the oxidation of PCT was greatly improved at the MWNTs-modified GC (MWNTs/GC) electrode as compared with the bare GC electrode, with relatively high sensitivity, stability and life time. Good linear relationship between the oxidation peak current and the PCT concentration in the range of 1 x 10(-7) to 1 x 10(-3) M (r = 0.996) was obtained in phosphate buffer solution (PBS) with pH 6.5, the detection limit was 2 x 10(-8) M (S/N = 3) by use of modified electrode. The proposed method was successfully applied to the PCT determination in tablets.
