摘要：

Two highly water-soluble amino acids,which derived fromβ-CDs,i.e.,glutamic acid-β-cyclodextrin(GluCD)and ethylene-diamine-β-cyclodextrin(EDCD),were synthesized and were examined for their effect on solubilization of anthracene(ANT),complexation of cadmium(Cd~(2+)),and elution removal of ANT and Cd~(2+)in soil.The results showed that GluCD and EDCD were powerful complexant for ANT and Cd~(2+).In the presence of 10 g/L GluCD and EDCD,the solubilization of ANT increased by 47.04 and 23.85 times compared to the control,respectively.GluCD resulte...
