Polymer Preprints (American Chemical Society, Division of Polymer Chemistry), 45(2), 523-524 (English) 2004 American Chemical Society, Division of Polymer Chemistry. CODEN: ACPPAY. ISSN: 0032-3934. DOCUMENT TYPE: Journal; (computer optical disk) CA Section: 61 (Water) Section cross-reference(s): 37 Removal of org. contaminants from water is a continuing environmental issue attracting new chemistries and engineering approaches. From a materials science standpoint, creation of solids which can bind org. substances with varying degrees of affinity are of considerable interest. 68-12-2 and 1768-64-5 are also in the experiment. The absorption properties of a series of bile acid-based resins were compared with an ionically-immobilized surfactant. Absorbent and polymer synthesis is described as are results of 4-chlorotetrahydropyran (CTHP) absorption from water. Results showed CTHP was sorbed with greater efficiency by the synthesized polymer and an ionically-immobilized surfactant sorbent. The feasibility of using covalently-attached, bile acid-based resins as hydrophobic sorbents and the ability to modulate their absorbing characteristics via sterol loading significantly extends the concept of hydrophobic sponges. In principle, such materials could have uses in areas other than water treatment. .
