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 کاملApplication of graphene oxide- magnetic nanoparticle for solid phase extraction of trace amounts of cadmium ions in environmental samples
Abstract In this work, Fe3O4-graphene oxide nanocomposite (GO-Fe3O4) was prepared as effective absorbent for magnetic solid phase extraction (MSPE) of trace quantities of cadmium ions in environmental water and rice samples using 1, 2-dihydroxy anthraquinone-3-sulphonic acid, sodium salt (Alizarin red S) and flame atomic absorption spectrometry (FAAS). The GO-Fe3O4 was characterized by scanni...

N-octyl-modified magnetite NPs for optimization of solid phase extraction for trace analysis of phenytoin in real samples
objective: Phenytoin is an anti-seizure medication used to treat epilepsy, as well as to control arrhythmias (irregular heartbeat) and to treat migraine headaches and nerve pain. It is recommended to determine the amount of this drug in the blood to control the seizure and prevent its toxicity. In the present study, a sensitive and simple procedure based on the dispersive solid phase extraction...
