Abstract
Two series of resins with both polar and nonpolar regions were synthesized by the introduction of a-oxoalkyl and a-hydroxyalkyl groups to a porous low crosslinked styrene-divinylbenzene. These resins showed higher adsorption capacity for nonionic and anionic surfactants than did the starting resin. Resins with shorter alkyl chains were particularly more effective than those with longer chains. The polar groups introduced contributed to the increase in adsorption of the surfactants. These resins were applied to pre-concentration of anionic surfactants in environmental specimen.
