Magnetic solid-phase extraction based on fluconazole-functionalized Fe3O4@SiO2 nanoparticles for the spectrophotometric determination of cationic dyes in environmental water samples

Magnetic‐Nanoparticle‐Based Dispersive Micro‐Solid Phase Extraction for the Determination of Crystal Violet in Environmental Water Samples

“…Extraction of CV was improved as the time of ultrasonic increased but above ultrasonic time 7.6 min (optimal elution time), the signals not the significant improvement or remained stable. This could be explained using the fact that the high surface contact between the adsorbent and dye was enhanced by the mass transfer and extraction efficiency [34–36] …”

Magnetic Solid Phase Extraction for Determination of Dyes in Food and Water Samples

“…Caramelized carbonaceous shell-coated γ-Fe 2 O 3 (γ-Fe 2 O 3 @CNM-based MSPE) coupled with LC-MS/MS was used for the extraction and analysis of MG and CV dyes in spring water, fishpond, lake, sea, and industrial wastewater, RSD below 5.2% for MG and RSD below 5.5% for CV dyes [87]. Cationic dyes (MG and CV) were extracted and determined using Fe 3 O 4 @SiO 2 -Flu followed by UV-Vis spectrophotometer in Caspian seawater and wastewater, and RSD was computed to be 4.77-4.17% [88]. Fe@NiAl-LDHs (layered double hydroxide) coupled with HPLC was used for the extraction and determination of Sudan red dyes in Ming Tombs Reservoir water, Changping Park water, and Binhe Park water, with low LOD from 0.002 to 0.005 μg/L [89].…”
