영문 초록

Surfactants, such as b-cyclodextrin (b-CD), have frequently been used to desorb hydrophobic organic compounds (HOCs) from the soil and to enhance the bioavailability of HOCs. This study was performed to investigate the binding characteristics between toluene and b-CD with batch experiment and the column study. The results showed that b-CD formed an efficient complex with toluene. As the b-CD concentration increased, the amount of toluene complexed with the b-CD rapidly increased, up to 40% of the initially added concentration at equilibrium. The effect of b-CD on the desorption of toluene from the soil in a water/soil system showed that as the b-CD concentration increased, the amount of toluene desorbed into the water increased up to 100% of their initial toluene concentrations. In the column experiment, toluene was effectively transported through the column in the presence of b-CD without sorption or retardation.
