研究了双酚A(BPA)在十二烷基硫酸钠(SDS)现场自组装膜与离子液体N-丁基吡啶夫氟磷酸盐([ bupy]PF6)复合修饰碳糊电极(SDS-[ bupy]PF6/CPE)上的电催化氧化行为和电化学动力学性质.实验结果表明,在SDS-[ bupy]PF6/CPE上BPA发生了一受扩散控制的不可逆电化学氧化过程,用循环伏安(CV)法和计时电流(CA)法测得BPA在SDS-[bupy]PF6/CPE上的电极反应过程动力学参数.用方波伏安(SWV)法测得BPA氧化峰电流(Ipa)与其浓度在1.0×10-5～ 1.0×10-3 mol/L范围内呈良好的线性关系,线性方程为Ipa(μA) =2.635 +51.30c( 10-3 mol/L),r =0.998 1,检测限(S/N=3)为3.01×10-7 mol/L,同时运用SWV法对湖水样品中双酚A的含量进行了电化学定量测定.
