摘要
采用循环伏安法 ,对对乙酰氨基酚在玻碳电极上的伏安行为进行了研究 ,并在 1 .0mol/L的盐酸溶液中得到一灵敏而尖锐的氧化峰 ,EP 为 +795mV(vs.Ag/AgCl)左右 ,峰电流与对乙酰氨基酚浓度在 6.6× 1 0 - 6~ 1 .32× 1 0 - 4 mol/L近 3个浓度范围内呈现良好的线性关系 .该法应用于扑热息痛药剂含量的测定 。
The voltammetric behaviour of paracetamol was investigated by cyclic voltammetry at a glassy carbon electrode.In a medium of 1.0?mol/L HCl solution,a high sensitivity oxidative peak was obtained.The oxidative current could be recorded for quantitative analysis.The method is simple and rapid.
