合成了1-[3＇-（N-吡咯）丙基]-3-丁基咪唑离子液体,采用电位阶跃技术制备了该离子液体聚合物膜修饰玻碳电极,利用扫描电子显微镜（SEM）和交流阻抗谱（EIS）表征了该膜修饰电极的表面形貌和电化学性能,通过伏安法研究了双酚A在该膜修饰电极上的电化学行为.结果表明：双酚A在聚离子液体膜修饰电极上只有一个不可逆氧化峰,氧化峰峰电流比在裸玻碳电极上显著增强.峰电流与双酚A浓度在1.0×10-8～1.0×10-5mol/L之间线性关系良好,检出限为8.0×10-9mol/L（S/N=3）.该法可用于测定塑料瓶中双酚A.

An ionic liquid 1-[3’-(N-Pyrrolyl) propyl]-3-butylimidazolium tetrafluoroborate was synthesized and used as a monomer to prepare a poly ionic liquid film modified glassy carbon electrode with potential step technique.The morphology and electrochemical properties of the obtained poly ionic liquid film electrode were characterized with SEM and EIS.The electrochemical behaviors of bisphenol A on the poly ionic liquid film electrode were also investigated with voltammetry.The results indicated that the electrochemical oxidation of bisphenol A at the poly ionic liquid film electrode has only one irreversible oxidation peak.Compared with the bare glassy carbon electrode,its oxidation peak current increased significantly.A good linear relationship between the current response and bisphenol A concentration was found in the range from 1.0×10-8 to 1.0×10-5 mol/L with a detection limit of 8.0×10-9 mol/L(S/N=3).The proposed method might be applied for the determination of bisphenol A in drinking bottle.
