영문 초록

Recently, surfactants were frequently used in order to desorb the hydrophobic organic compounds (HOCs) from soil and to enhance the bioavailability. Among them, j3-cyclodextrin (B-CD) is one of those. This study was performed to investigate the binding characteristics between benzene and B-CD and to examine the bioavailability of benzene. First, we investigated binding charasteristics between benzene and B-CD in waterand water/soil system. Then, we examined the effect of B-CD on the biodegradation of benzene in water and water/soil system. Experimental results on the binding characteristics showed that I3-CD resulted in an efficient complex formation with benzene. As B-CD concentration increased, the benzene concentration complexed with B-CD rapidly increased to 30-40% initial benzene added, and reached the equilibrium. We also investigated the effect of B-CD on the desorption of benzene from soil in the water/ soil system. As I3-CD concentration increased, benzene concentration desorbed into water increased up to 90%. However, in its application to biodegradation of benzene in water and water/soil system, the biodegradation rate of benzene did not improved in the presence of B-CD compared with in the absense of B-CD. This result indicated that V was more preferentially used as a carbon source than benzene. Therefore, for remediation of benzene contaminated soils, B-CD can be used as a surfactant to desorb benzene from soil, and then ex-situ chemical treatment can be applied for the remediation.
