构建了一种基于碳纳米管-离子液体复合电极的双酚A（ BPA）传感器。采用循环伏安法和线性扫描伏安法（ LSV）研究了双酚A在该修饰电极上的电化学行为，并对实验条件进行了优化。在最佳条件下， BPA 的氧化峰电流与其浓度在0.5～100μM范围内有良好的线性关系（r2＝0.9980），检出限为0.1μM（S/N＝3）。此方法能应用于湖水和塑料袋中BPA的测定，回收率在96.20％～105.20％之间。

The bisphenol A ( BPA ) sensor was fabricated successfully based on carbon nanotubes ionic liquid composite electrode ( MWNTs/CILE ).Electrochemical behaviors of bisphenol A at the modified electrodes were investigated by cyclic voltammetry and linear sweep voltammetry ( LSV ).Experimental conditions that influenced the analytical performance of the MWNTs/CILE were optimized.Under optimal conditions , the electrochemical sensor exhibited a wider linearity range from 0.5 μM to 100 μM BPA with a detection limit of 0.1 μM(S/N=3).This method was successfully applied to determine BPA leached from plastic bag and lake water with good recovery , ranging from 96.20%to 105.20%.
