Abstract
Sorption of aqueous phenol on organoclays mixtures was determined. Hexadecyltrimethyl ammonium bromide (HDTMA), dihexadecyldimethyl ammonium bromide (DHDDMA), trihexadecylmethyl ammonium bromide (THDMA) and tetrahexadecyl ammonium chloride (THDA) salts were added to cheto bentonite. Aqueous phenol sorption was monitored by UV-vis spectrometry and gas-liquid chromatography. It was observed that as the surfactant C16 alkyl side chains increased, the phenol sorption of organoclay decreased. The optimum cation exchange capacity (CEC) for the organoclays, specifically those containing HDTMA and THDMA was 2 to 2.5 meq/g surfactant per g clay.
