Abstract

This study investigates the possibility of monoaromatic compounds benzene and toluene adsorption onto alginate gel (AG-AC) beads with impregnated activated carbon and their regeneration possibility using ultrasound method. Kinetic adsorption tests showed that the AG-AC beads were capable of removing the organic compounds from either individual or mixed compound solutions. Removal ratio of the AG-AC beads was as high as that of free PAC powder for benzene and toluene. The removal was more efficient for toluene (97%) than for benzene (75%), and slightly decreased by 7% and 5% for toluene and benzene respectively even after 5 times regeneration. This indicates that the regeneration method utilizing ultrasound is very efficient for desorption of benzene and toluene from the AG-AC beads developed in this study.
