EPA Method 630.1:
The Determination of Dithiocarbamates Pesticides in Municipal and Industrial Wastewater

A measured 5-mL volume of sample is digested with acid to yield CS2 by hydrolysis of the dithiocarbamate moiety. The evolved CS2 is extracted from water into hexane. Gas chromatographic conditions are described which permit the separation and measurement of CS2 in the extract by gas chromatography with a Hall detector in the sulfur mode.

This method covers the determination of certain dithiocarbamates pesticides after conversion to carbon disulfide.
