Method of removing organic contaminants from air and water with organophilic, quaternary phosphonium ion-exchanged smectite clays |
| abstract |
An quaternary phosphonium ion-exchanged clay and method of removing organic contaminants from air and/or water, by contacting the contaminants in the air or water with a quaternary phosphonium organo-clay. The clay is prepared by ion-exchange of an ion-exchangeable clay with (a) tetra-short chain alkyl (C 1 -C 4 ) quaternary phosphonium ion or (b) a di- or tri-short chain alkyl (C 1 -C 4 ) quaternary phosphonium ion having 1 or 2 mono-substituted or unsubstituted cycloakyl moieties, or one or two alkaryl moieties for removing air-laden and water-laden organic contaminants. The new organo-clays and methods are particularly adapted for removal of aromatic petroleum-based contaminants from water, such as benzene; alkylbenzenes, such as toluene; xylenes (o-, m- and p-isomers); and chlorinated 1 and 2 carbon compounds, such as CCl 4 . |
