Four different SPE cartridges were tested for extracting six triazines, including atrazine, simazine, prometryn, desethylatrazine, 2-hydroxyatrazine and desisopropylatrazine, and finally ENVI-18 was selected as optimal. The method for solid phase extraction was further systematically studied for details.
