The Extraction of Diquat and Paraquat for EPA Method 549.2 using the SmartPrep Automated Cartridge Extractor
30 May 2013
Diquat and paraquat are some of the most widely used and available herbicides in the world. They are fast-acting, non-selective quaternary amines used mainly in the agricultural industries to control the penetration of invasive plants and crop yield. Both diquat and paraquat are toxic to humans upon exposure, thus their levels must be carefully controlled. This application note from Horizon Technology outlines a method for the extraction of diquat and paraquat from water samples using the SmartPrep Automated Solid Phase Cartridge Extractor.
