摘　　要：采用电化学技术研究了盐酸克伦特罗(CLB)在玻碳电极上的电化学还原行为。在pH4.54的Britton Robinson缓冲液中,CLB于+0.38V(vs.Ag AgCl)左右处出现一个明显的方波溶出伏安还原峰,峰电流与CLB的浓度在3.0×10-7～1.0×10-5mol L范围内呈良好的线性关系,检出限为5.1×10-8mol L。该法可应用于模拟兔血清及尿样中CLB的测定。The voltammetric behavior of clenbuterol was investigated by cyclic voltammetry, linear sweep voltammetry, osteryoung square wave voltammetry, chronocoulometry and bulk electrolysis with coulometry at a glassy carbon electrode. In BR buffer(pH 4.54), CLB gave an obvious reduction peak at 0.38 V (vs. Ag/AgCl) by square wave stripping voltammetry. The peak current is proportional to the concentration of CLB over the rage of 3.0×10^(-7)～1.0×10^(-5) mol/L. The detection limit is 5.1×10^(-8) mol/L. The method was applied to the assay of CLB in rabbit serum and urine with satisfactory results.
