Analvsis of Organophosphorus Pesticides in Water by Graphitized Carbon Black Extraction and Gas Chromatouraphy-Mass Spectrometry
Keywords: organophosphorus pesticides, solid-phase extraction, carbopack, gas chromatography/mass spectrometry, water analysis
AbstractA solid-phase extraction (SPE) procedure using graphitized carbon black (GCB) was developed to study organophosphorus pesticides (OPs) in natural water samples. Determination was carried out by gas chromatography-mass spectrometry (GC-MS) using single-ion monitoring. The pesticides investigated include heptenophos, diazinon, chlorpyrifos methyl, parathion methyl, paraoxon, fenitrothion, malathion, parathion ethyl, phosalone, and azinphos ethyl. Recoveries in different water samples ranged from 38 to 161% and the standard deviations were from 0.9 to 31%. The detection limits ranged from 0.1 to 8 ng/L. The method described here has practical applications to environmental investigations that require trace analysis of OP compounds in water.
