摘要
在0.1mol/LH2SO4底液中,用碳糊电极吸附伏安法测定多巴酚丁胺,阳极峰电位为0.46V(vs.SCE),峰电流与多巴酚丁胺的浓度在3.0×10-9~1.0×10-6mol/L范围内呈良好的线性关系.该法检测下限为1.5×10-9mol/L,回收范围为94.00%~102.59%,相对标准偏差为3.1%(n=9).本文还对反应机理进行了初步探讨.
Dobutamine is determined by adsorptive voltammetry using a carbon paste electrode in a base solution of 0 1 mol/L H 2SO 4. 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 3 0×10 -9  ̄1 0×10 -6 mol/L. The detection limit of the method is 1 5×10 -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.
