Extraction of fluoxetine from aquatic and urine samples using sodium dodecyl sulfate-coated iron oxide magnetic nanoparticles followed by spectrofluorimetric determination

Determination of UV Absorbers and Light Stabilizers in Food Packing Bags by Magnetic Solid Phase Extraction Followed by High Performance Liquid Chromatography

“…4, with increasing CTAB, the adsorption capacities of the analytes are increasing. This phenomenon can be explained by the progressive formation of mixed hemimicelles (hemimicelles and admicelles) on the surface of the adsorbent [32,33]. But excess CTAB decreases the recovery of the analytes due to the formation of CTAB micelles in the bulk solution causing the analyte to redistribute into the solution.…”

Silane modified magnetic nanoparticles as a novel adsorbent for determination of morphine at trace levels in human hair samples by high-performance liquid chromatography with diode array detection

“…Finally MNPs were stored in 100 mL degassed water under the N 2 atmosphere. The density of the suspended solution was found to be 23 mg mL -1 [43].…”

In-tube magnetic solid phase microextraction of some fluoroquinolones based on the use of sodium dodecyl sulfate coated Fe3O4 nanoparticles packed tube

“…One of these modifications which is based on the adsorption of surfactants such as sodium dodecyl sulfate (SDS) at solid-liquid interface to form mixed hemimicelles (hemimicelles and admicelles) has been studied extensively and applied for the preconcentration of a variety of analytes from complex environmental matrices [15][16][17][18]. The SDS coated Fe 3 O 4 NPs have been reported in 2011 for isolation and preconcentration of fluoxetine form aquatic and biological samples [15]. Furthermore, the SDS coated Fe 3 O 4 NPs have been reported for the extraction of trace amount of mercury [16].…”
