A new, simple, and effective procedure using poly(3,4-ethylenedioxythiophene)/lignosulfonate electropolymerized sorbent solid-phase microextraction (PEDOT/LS-SPME) combined with LC-MS/MS for determination of bisphenols in environmental water samples was developed. Various parameters influencing the performance of the analytical procedure including the type of sorbent, electropolymerization time, sorbent preconditioning time, extraction time, desorption (time and solvent), and sample pH were investigated and optimized. Under optimal conditions the proposed method allowed us to achieve good precision (n = 5) between 6.0 and 12.1%. The limits of detection were equal to 0.17 μg L⁻¹ for BPA, 0.16 μg L⁻¹ for BPF, 0.07 μg L⁻¹ for BPE, 0.05 μg L⁻¹ for BPB, and 0.027 μg L⁻¹ for BPAF. The proposed method was successfully applied for the determination of bisphenols in aqueous environmental samples.

电聚合聚（3,4-乙撑二氧噻吩）吸附剂在双酚固相微萃取中的应用

建立了使用聚（3,4-乙撑二氧噻吩）/木素磺酸盐电聚合吸附剂固相微萃取（PEDOT / LS-SPME）结合LC-MS / MS的新方法，该方法简单，有效，可用于测定环境水样中的双酚。研究和优化了影响分析程序性能的各种参数，包括吸附剂类型，电聚合时间，吸附剂预处理时间，萃取时间，脱附（时间和溶剂）以及样品pH值。在最佳条件下，所提出的方法使我们能够在6.0至12.1％之间达到良好的精度（n = 5）。检测限为等于0.17微克大号^-1为BPA，0.16微克大号^-1为BPF，0.07微克大号^-1为BPE，0.05微克大号^-1为BPB，和0.027微克大号^-1为BPAF。该方法成功地用于环境水样中双酚的测定。
