Removal of Organic Compounds from Water Via Adsorption Onto Polymethylhydrosiloxane Pentenyl-Β-Cyclodextrin
Abstract
A co-polymer of polymethylhydrosiloxane and pentenyl-β-cyclodextrin (PMSP-β -CD) is synthesized and used to extract various aromatic materials from water by adsorption onto the co-polymer matrix. The method of synthesis, separation scheme and parameters associated with adsorption are discussed. Salt and pH effects are also examined. The problems associated with other methods of removal are compared with those encountered by extraction using PMSP-β -CD. Most compounds studied can be quantitatively extracted from water if the extraction conditions are optimized. Removal is not greatly influenced by the addition of salt or change in pH. PMSP-β -CD is easily recycled at 80-100°C and both the organic analytes and PMSP-β -CD are recovered with a high efficiency. The results also indicate that extractions using PMSP-β -CD are not only possible but also advantageous in some cases. © 1994, Taylor & Francis Group, LLC. All rights reserved.
