Herein, an efficient graphene oxide/Fe3O4@polythionine (GO/Fe3O4/PTh) nanocomposite sorbent was introduced for magnetic solid-phase extraction combined with high-performance liquid chromatography–ultraviolet detection of duloxetine (DLX) in human plasma. To prepare the sorbent, an oxidative polymerization of thionine on the surface of magnetic GO was utilized while PTh was simply used as a surface...
An efficient analytical method called ionic‐liquid‐based ultrasound‐assisted in situ solvent formation microextraction followed by high‐performance liquid chromatography was developed for the determination of atenolol in human plasma. A hydrophobic ionic liquid (1‐butyl‐3‐methylimidazolium hexafluorophosphate) was formed by the addition of a hydrophilic ionic liquid (1‐butyl‐3‐methylimidazolium tetrafluoroborate)...
A simple and sensitive methodology based on liquid–liquid–liquid microextraction (LLLME) followed by high-performance liquid chromatography-ultraviolet detection (HPLC-UV) has been successfully developed for the determination of atorvastatin (AT) in human plasma. AT was first extracted from 4.5mL acidic aqueous sample (diluted plasma, donor phase, pH 1) at temperature 45°C through 400μL 1-octanol...
