The simultaneous extraction of acidic, basic and amphiprotic pollutants from various samples is a considerable and disputable concept in sample preparation strategies. In this study, for the first time, coextraction of acidic, basic and amphiprotic pollutants (polar and apolar) with multiwalled carbon nanotubes/Fe₃O₄@polypyrrole (MWCNTs/Fe₃O₄@PPy) composite based dispersive micro-solid phase extraction followed by high performance liquid chromatography-photo diode array detection was introduced. Firstly, the extraction efficiency of various magnetic nanosorbents including Fe₃O₄, MWCNTs/Fe₃O₄, graphene oxide/Fe₃O₄ (GO/Fe₃O₄), Fe₃O₄@PPy, MWCNTs/Fe₃O₄@PPy and GO/Fe₃O₄@PPy were compared. The results revealed that MWCNTs/Fe₃O₄@PPy nanocomposite has higher extraction efficiency for five selected model analytes (4-nitrophenol, 3-nitroaniline, 2,4-dichloroaniline, 3,4 …
