In this study, an electrochemically enhanced solid-phase microextraction (EE-SPME) approach based on molecularly imprinted polypyrrole/multi-walled carbon nanotubes (MIPPy/MWCNTs) composite coating on Pt wire was developed for selective extraction of fluoroquinolone antibiotics (FQs) in aqueous samples. During the extraction, a direct current potential was applied to the MIPPy/MWCNTs/Pt fiber as working electrode in a standard three-electrode system, FQ ions suffered electrophoretic transfer to… CONTINUE READING
