摘　　要：目的 利用电位分析法测定硫酸沙丁胺醇的含量,为检测猪肉中硫酸沙丁胺醇的含量提供快速测定的方法。方法以硫酸沙丁胺醇与碘汞酸形成的缔合物为电活性物制备了硫酸沙丁胺醇碳糊电极,并对其各项性能进行测定。结果结果表明该电极对硫酸沙丁胺醇有很好的能斯特响应,电极线性响应范围为1.0×10^-1~1.0×10^-5mol/L,级差电位为28m V/p C,检测下限为：4.8×10^-6mol/L。结论 本方法简便快捷,适用于猪肉中硫酸沙丁胺醇含量的快速检测。Objective To measure the content of salbutamol sulfate by potential analysis to provide a rapid determination method for detecting content of salbutamol sulfate in pork. Methods Salbutamol sulfate carbon paste electrode was made with salbutamol sul- fate and iodomercurate complex as electrical active material, whose properties were tested. Results Good Nernst response for salbuta- tool sulfate was obtained. The developed method exhibited good linearity over the range from 1.0 × 10^ -1 - 1.0 × 10^-5 mol/L with a slope of 28 mV/pC and the detection limit was 4. 8 × 10^ -6 mol/L. Conclusion The method was simple and efficient for determination of the contents of salbutamol sulfate in pork sample.
