Characterizing the Photodegradation Ability of Pentachlorophenol in β-Cyclodextrin Soil Washing Solution

Abstract:

The objective of this study was to characterize the photodegradation ability of pentachlorophenol (PCP) in β-cyclodextrin (β-CD) soil washing solution. After contaminated soil remediation by β-CD soil washing method, solution contained target contaminant was further treated with photodegradation technique. Degradation processes with Xe lamp to simulate natural sun light was investigated under different temperature, and various aeration rate. TiO₂ employed as photocatalyst was also tested in the soil washing system. The result demonstrated that photodegradation rate of PCP in soil washing solution was related to the aeration rate. The reaction could be slightly accelerated by increasing the temperature. TiO₂ adding will decrease the degradation speed, while using it together with H₂O₂ will extremely increase the degradation rate of the target contaminant in this condition.
