Abstract:A fast and environment-friendly analytical method was implemented to determine multiclass pesticides in river sediments. Twenty-three pesticidesorganochlorine pesticides, organophosphorus pesticides, and triazines-were extracted via matrix solid-phase dispersion (MSPD) and analyzed by gas chromatography-tandem mass spectrometry (GC-MS/MS). Florisil demonstrated excellent analytes uptake capability as the extractant phase, with suitable selectivity for treating complex sediment samples. Under defined extraction… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
