英文摘要	采用电聚合方法将茜素红（AR）非共价修饰到多壁碳纳米管（MWCNTs）上，制得了PAR/MWCNTs/GC电极，该电极对叶酸（FA）具有良好的电催化作用. 结果表明，在最佳实验条件下，在-0.63 V处叶酸还原峰电流与浓度（1.25×10-6 ~ 4.00×10-5 mol·L-1）呈现良好线性关系，相关系数0.9985. 用标准加入法检测了回收率，其值达92.0% ~ 102.0%. 该电极制作简单，有良好的稳定性．; The novel modified electrode was fabricated by electropolymerizing alizarin red onto the surface of multi-walled carbon nanotubes on glassy carbon electrode surface, which exhibited good electrocatalytic activity for folic acid. The experimental results showed that the reduction peak current of folic acid at -0.63 V was linear to its concentration over the range of 1.25×10-6 ~ 4.00×10-5 mol·L-1 in the optimized experimental conditions (R = 0.9985). Test for recovery was carried out by standard addition method, and the recovery ratios were in the range of 92.0% ~ 102.0%. The modified electrode was prepared simply with excellent stability, which provides a new feasible method for determination of folic acid.; 河南省教育厅科学技术研究重点计划项目（No.13A150077）资助; 作者联系地址：河南大学化学化工学院环境与分析科学研究所，河南开封 475004; Author's Address: Institute of Environmental and Analytical Sciences, College of Chemistry and Chemical Engineering, Henan University, Kaifeng 475004, Henan, China; 通讯作者E-mail：lilyqujy@126.com
