Determination of bisphenols in environmental water samples using polydopamine-coated magnetic Fe₃O₄ as a magnetic solid-phase extraction material coupled with high-performance liquid chromatography

Abstract

Fe3O4@polydopamine composites were synthesized and used as a magnetic adsorbent to extract bisphenols from environmental water samples before determination using HPLC.

Multifunctional Thin Films and Coatings from Caffeic Acid and a Cross-Linking Diamine

“…Deposition of thin films from organic molecules or polymers is an increasingly used strategy to confer specific physical or chemical properties to materials and devices for a variety of biomedical and technological applications. , A paradigm methodology in this context relies on polydopamine (PDA), − a eumelanin-like material with universal adhesion and coating properties inspired to catechol- and amine-rich mussel byssus proteins . By dip-coating into a dopamine solution in Tris buffer at pH 8.5 , it is possible to functionalize and modify virtually any surface, enabling conjugation with biomolecules to obtain biomaterials for tissue engineering and surface tailoring for energetic, environmental, and analytical purposes.…”

Aminosilanized magnetic carbon microspheres for the magnetic solid‐phase extraction of bisphenol A, bisphenol AF, and tetrabromobisphenol A from environmental water samples

“…Magnetic adsorbents play an important role in the MSPE of various analytes, causing many researchers to focus on exploring novel MSPE adsorbents . Multiple magnetic materials have been used to extract trace bisphenols from environmental water samples, such as Fe 3 O 4 /graphene quantum dots (Fe 3 O 4 /GQDs) magnetic nanocomposite , iron‐ferric oxide/graphene oxide composite (Fe@Fe 2 O 3 /GO) , polydopamine‐coated magnetic Fe 3 O 4 composites (Fe 3 O 4 @PDA) , and ionic liquid (IL) coated magnetic Fe 3 O 4 nanoparticles (NPs) . However, the most magnetic sorbents are based on iron oxides that are vulnerable under acidic conditions.…”
