A simple and effective pretreatment method based on matrix solid-phase dispersion was developed for the determination of pharmaceutical and personal care products (PPCPs) and their metabolites in fish by high-performance liquid chromatog. tandem mass spectrometry. The type and amount of dispersant, adsorbent, and eluting solvent were optimized by a single-factor experiment and Box-Behnken design. Under the optimal conditions with 2.5 g of Florisil as a dispersant, 500 mg of C₁₈ as an adsorbent, and 5 mL of acetonitrile as an eluting solvent, the recoveries ranged from 70.4 to 99.9% with relative standard deviations less than 10.5%, and the limits of quantitation ranged from 0.13 to 1.01μg/kg. The developed method was successfully applied to detect PPCPs in marketed fish, and five PPCPs, including triclocarban, sulfadiazine, sulfadimidine, sulfamethoxazole, and carbamazepine, were detected at trace levels. The proposed method, which has the advantages of short anal. time, less solvent consumption, and high sensitivity, can be used for the determination of trace PPCPs in fish.

M.. And the article was included in Journal of Molecular Liquids in 2022.Name: 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride This article mentions the following:

Three gemini non-ionic surfactant-based polyethylene oxide with variable hydrophobic tails; 8 carbons (GPEOC), 12 carbons (GPEOL), and 16 carbons (GPEOP) have been synthesized successfully. The synthesized gemini surfactant regulated the preparation of the nano-catalyst AgNPs for toxic materials removal. The AgNPs were prepared via photo-chem. reduction reaction based on using the sun light and the gemini surfactants as reducing and capping agents, resp. The surfactant′s tail exhibited a substantial impact on regulating the AgNPs preparation as confirmed by TEM, UV-vis, and DLS measurements. The surfactant GPEOP produced AgNPs with a uniform, dispersibility and smaller particles size 14.8 ± 5.4 nm comparing to other two gemini surfactants GPEOC and GPEOL with shorter hydrophobic tail. The surface and thermodn. performance of the GPEOC, GPEOL and GPEOP gemini non-ionic surfactants were dependent on both solution temperature and surfactant′s tail hydrophobicity. The adsorption ability is significantly improved as functional of temperature or hydrophobicity. Elongation the surfactant′s tail and increasing the temperature, promote lowering the critical micelle concentration and enhance the adsorption affinity at interfaces. The study was extended to investigate how the surfactant′s tail improve the catalytic performance of the AgNPs-based catalyst. The surfactant′s tail controlled the catalytic performance of the AgNPs regarding the methylene blue and p-nitrophenol removal, where the GPEOP/AgNPs exhibited highest catalytic activity. Addnl., the surfactant′s tail controlled the antimicrobial of the prepared surfactant and surfactant/AgNPs hybrid system.
