| Abstract: | Dobutamine is determined by adsorptive voltammetry using a carbon paste electrode in a base solution of 01 mol/L H2SO4. The peak potential of anode is 0.46 V(vs. SCE). There is a good linear relationship between the peak current and the concentration of dobutamine in the range of 30×10-9 ～10×10-6 mol/L. The detection limit of the method is 15×10-9 mol/L. The recovery is 94.00%～102.59%, and the relative standard deviation is 3.1%(n =9). The possible reaction mechanism is discussed. |
