Coacervative Extraction of Priority Carcinogenic PAHs from Water for LC Analysis
Researchers from Edificio Anexo Marie Curie (Cordoba, Spain) used coacervates of decanoic acid reverse micelles to extract priority carcinogenic polycyclic aromatic hydrocarbons (PAHs) in waste and surface water for subsequent analysis by liquid chromatography-fluorimetry.
Researchers from Edificio Anexo Marie Curie (Cordoba, Spain) used coacervates of decanoic acid reverse micelles to extract priority carcinogenic polycyclic aromatic hydrocarbons (PAHs) in waste and surface water for subsequent analysis by liquid chromatography-fluorimetry. The researchers stirred filtered aqueous samples with tetrahydrofuran containing decanoic acid to form a coacervate containing the PAHs. The coacervate reportedly prevents the PAHs from adsorption onto container surfaces during sample storage, and no clean-up steps are necessary.
Extracting Estrogenic Hormones Using Rotating Disk and Modified Clays
April 14th 2025University of Caldas and University of Chile researchers extracted estrogenic hormones from wastewater samples using rotating disk sorption extraction. After extraction, the concentrated analytes were measured using liquid chromatography coupled with photodiode array detection (HPLC-PDA).
Polysorbate Quantification and Degradation Analysis via LC and Charged Aerosol Detection
