EPA Method 646:
The Determination of Dinitro Aromatic Pesticides in Municipal and Industrial Wastewater

Summary:
Dinitroaromatic pesticides are removed from the sample matrix by extraction with 15% methylene chloride in hexane. The extract is dried, exchanged into hexane, and analyzed by gas chromatography (GC). Column chromatography is used as necessary to eliminate interferences which may be encountered. Measurement of the pesticides is accomplished with an electron capture detector.

Scope:
This method covers the determination of certain dinitro aromatic pesticides in municipal and industrial wastewater.
