Device for sequestration and concentration of polar organic chemicals from water |
摘要 |
A device is provided for the sequestration and concentration of polar chemicals from water. The device includes a microporous hydrophilic membrane enclosure formed by a tube or facing membranes. A mixed sequestration media, contained within the enclosure, transforms dissolved polar organic chemicals into non-mobile species. The sequestration media is a triphasic admixture of a hyper-crosslinked polystyrene-divinylbenzene resin, and a carbonaceous sorbent dispersed on a size exclusion styrene-divinylbenzene copolymer.
