Ci8 Empore extraction disks were used for the isolation and trace enrichment of phenylureas in 1 L of river water [68]. Triazines and aryl phenoxy acid herbicides were extracted with good recovery by 0.5 L tap water and 0.1 L groundwater [31,69,70] by PS-DVB disks. A combination of the SPE disk technology for extracting analytes in water and supercritical fluid extraction technology for reextracting analytes from disks has been applied to the analysis of metsulfuron-methyl and chlorsulfuron [71]. Phenylureas and triazines were isolated from water and soil extracts by SPE using a layered system of two extraction disks [72]. The first disk consisted of a SAX material imbedded in Teflon, and the second disk, used as a cleanup device, was made of Cis particles also imbedded in Teflon.
