Efficient magnetic sorbent for extracting bisphenol A from aqueous samples.

ABSTRACT: Magnetic polymer sorbents were developed and evaluated for the extraction of bisphenol A (BPA) from aqueous solution using magnetic solid-phase extraction (MSPE) coupled with high-performance liquid chromatography with UV detection (HPLC-UV). Two sorbents were synthesized by modifying amine-terminated polydimethylsiloxane (PDMS) with 3-aminopropyltriethoxysilane (APTS): MPCNT, prepared with carboxyl-functionalized multi-walled carbon nanotubes (MWCNT-COOH), and MPTCl, synthesized without MWCNT-COOH and cross-linked with terephthaloyl chloride. Incorporation of MWCNT-COOH introduced additional π-π interactions, hydrogen bonding, and hydrophobic domains, which significantly enhanced BPA uptake. Various analytical techniques were employed to characterize the morphology, thermal properties, an
