Restricted access polypyrrole employed in pipette-tip solid-phase extraction for determination of nimodipine and nicardipine in breast milk

Abstract

A HPLC-UV method for the determination of nimodipine and nicardipine in breast milk using restricted access polypyrrole as adsorbent in pipette-tip solid-phase extraction (PT-SPE) have been developed. The chromatographic conditions...

Poly(aniline‐co‐pyrrole) as Adsorbent for Removal of Pharmaceuticals: Preparation, Characterization, Kinetics, Isotherms and Application on Sample Preparation

“…[4] Conducting polymers and/or their composites have been extensively investigated as efficient adsorbents for various PhACs, [7,[11][12][13][14][15] because of the desirable properties including chemical and thermal stability, low cost, easy synthesis etc. [16][17][18][19][20] The combination of polypyrrole and polyaniline into a single adsorbent material can improve its adsorption properties.…”

“…Many materials, such as carbon‐based materials including active charcoal/biochar, graphene/graphene oxide, carbon nanotubes and its derivatives, were employed to remove PhACs from aqueous matrices and to apply in separation science [4] . Conducting polymers and/or their composites have been extensively investigated as efficient adsorbents for various PhACs, [7,11–15] because of the desirable properties including chemical and thermal stability, low cost, easy synthesis etc [16–20] . The combination of polypyrrole and polyaniline into a single adsorbent material can improve its adsorption properties.…”
