| 摘 要： | 研究了氯霉素(CAP)在多壁碳纳米管修饰玻碳电极上的电化学行为.发现在pH=2.0的0.1 mol/LKCl-HCl底液中,CAP在该修饰电极上有一灵敏的还原峰(Ep=-0.36 V vs.Ag/AgCl),峰电流与CAP浓度成正比,线性范围为6.0×10-6~2.7×10-4mol/L,检测限达3.0×10-6mol/L.该方法灵敏、准确,用于模拟样品和实际样品的测定,结果满意.

| Abstract: | A sensitive electrochemical method was developed for determination of chloramphenicol(CAP) using a glassy carbon electrode modified with multi-wall carbon nanotubes(MWNTs) film.In 0.1 mol/L KCl-HCl solution of pH 2.0,a sensitive cathodic peak of CAP on the MWNTs modified electrode was obtained at around-0.36 V(vs Ag/AgCl).Under the optimum conditions,the reduction peak current was linearly proportional with the concentration of CAP over the range of 6.0×10-6 to 2.7×10-4 mol/L with a detection limit of 3.0×10-6 mol/L.The proposed method is sensitive and accurate,and can be applied to determine CAP in simulated samples and real samples with satisfactory results. |
