%X To improve the water solubility of β-cyclodextrin,β-cyclodextrin reacted with glycine in the presence of KOH and epichlorohydrin in water,a high water soluble glycine-β-cyclodextrin was prepared.Glycine-β-cyclodextrin for enhancing the solubilization and desorption behavior of anthrancene in soil were studied.The influence factors on desorption of anthrancene,such as pH,initial concentration of glycine-β-cyclodextrin,temperature and CD type were also investigated and described in details.The results showed that glycine-β-cyclodextrin has obvious solubilization for anthrancene,the solubility of anthrancene in 50 g/L of glycine-β-cyclodextrin was enhanced about 20-fold,the desorption efficiency of glycine-β-cyclodextrin for anthrancene in soil decreases with increasing pH,high temperature and initial concentration of glycine-β-cyclodextrin were beneficial to the desorption of anthrancene in soil,the desorption efficiency of glycine-β-cyclodextrin for anthrancene in soil was higher than those of α-cyclodextrin and β-cyclodextrin for anthrancene in soil and the desorption of glycine-β-cyclodextrin for anthrancene in soil followed the pseudo-second-order rate equation.This static desorption research could provide some fundamental information for the remediation of anthrancene-contaminated soil.
