The Use of Support-bonded Silicones for the Extration of Organochlorines of Interest from Water

Water was spiked with various types of chlorinated organics at trace levels, in an effort to demonstrate the pontential of support-bonded silicones to collect these pollutants from natural aqueous systems. Greater amounts of the spiked water were pumped through a bed of a silicone phase, followed by a small amount of pentane. The pentane eluted the collected organochlorines, ready for determination by electron capture gas chromatography. This approach proved successfl for most model compounds of parts per trillion levels. © 1972.
