Method 622
The Determination of Organophosphorus Pesticides in Municipal and Industrial Wastewater
Scope
This method covers the determination of certain organophosphorus pesticides.
This is a gas chromatographic (GC) method applicable to the determination of the compounds listed above in industrial and municipal discharges as provided under 40 CFR 136.1.
A measured volume of sample, approximately 1 L, is extracted with 15% methylene chloride using a separatory funnel. The methylene chloride extract is dried and exchanged to hexane during concentration to a volume of 10 mL or less. Gas chromatographic conditions are described which permit the separation and measurement of the compounds in the extract by gas chromatography with a thermionic bead or flame photometric detector in the phosphorus mode.
