Solid Phase Extraction Using Modified Magnetic Iron Oxide Nanoparticles for Extraction and Spectrofluorimetric Determination of Carvedilol in Human Plasma Samples
A new analytical approach was developed involving magnetic solid–phase extraction and spectrofluorimetric determination of carvedilol in human plasma samples. A plasma sample was prepared and adjusted to pH 8.2–10, then carvedilol was quickly extracted using iron oxide magnetic nanoparticles modified by the surfactant cetyltrimethylammonium bromide and determined to apply spectrofluorimetry...
متن کاملSpectrophotometric Determination of Mefenamic Acid in Biological Samples Using Magnetic Iron Oxide Nanoparticles as a Sorbent for Solid Phase Extraction
This work investigates the potential of magnetic Fe3O4 nanoparticles as an adsorbent for separation and preconcentration of trace amounts of mefenamic acid in aquatic and biological samples, prior to spectrophotometric determination. The magnetic iron oxide nanoparticles (MIONs) were synthesized by mixing of ferrous and ferric chlorides. The possible parameters affecting the enrichment were opt...
متن کاملMagnetic Solid-Phase Extraction Based on β-Cyclodextrins/Acrylic Acid Modified Magnetic Gelatin for Determination of Moxidectin in Milk Samples
β-Cyclodextrins/acrylic acid modified magnetic gelatin was prepared and then employed as the magnetic solid-phase extraction (MSPE) sorbent for extraction of moxidectin in milk samples. Due to the rigidity of hydrophobic cavity of β-cyclodextrins and carboxyl groups of acrylic acid, magnetic composites are prepared to form a complex with target molecules through various kinds of chemical reacti...
متن کاملPreparation of Sodium Dodecyl Sulfate Modified Pyrrolidine-1-dithiocarboxylic acid Ammonium Coated Magnetite Nanoparticles for Magnetic Solid Phase Extraction of Pb(II) from Water Samples
This paper describes the development of a procedure for Pb(II) ions removal from various water samples after magnetic solid phase extraction (MNPs) by magnetite nanoparticles (Fe3O4 NPs) modified with sodium dodecyl sulfate (SDS) and pyrrolidine-1-dithiocarboxylic acid ammonium (PDTCAA). The synthesis of Fe3O4 NPs was certified by characterization techniques including field emission scanning el...
