| 中文摘要:制备了以纳米Fe2O3为修饰剂的涂碳型硫酸沙丁胺醇选择电极，采用电位分析方法对其各项性能进行测定。结果表明，该纳米Fe2O3修饰电极有很好的能斯特响应，其线性范围为1.0×10-6~ 0.1 mol/L，级差电位为59 mV/pC，与普通电极相比，响应时间较短(10 s)，检出限更低(2.8×10-7 mol/L)。将修饰电极应用于猪肉样品中硫酸沙丁胺醇含量的测定，结果与标准方法结果相符。 |

| Abstract:A potentiometric method was developed for the determination of salbutamol sulfate by using a novel carbon coated polyvinyl chloride membrane salbutamol sulfate selective electrode modified with nano-Fe2O3.The prepared electrode showed a good Nernst response in the linear range of 1.0×10-6-0.1 mol/L with a slope of 59 mV/pC.Compared to the unmodified electrode，the electrode modified with nano-Fe2O3 exhibited a faster response time(10 s) and a lower detection limit(2.8×10-7 mol/L).The modified electrode was applied in the determination of salbutamol sulfate in pork samples， and the results were in agreement with those obtained by the standard method. |
