The adsorption isotherms of phenol and bisphenol A onto bamboo charcoals were measured in aqueous solution at 25℃. The bamboo charcoals used were different types of refinement degree prepared from different route temperature. In general, the adsorption affinities for phenol and bisphenol A increased with decreases in the refinement degree of bamboo charcoals. Phenol adsorbed about 10 times greater than bisphenol A. Adsorption affinities of phenol accelerated in the presence of additives such as β-cyclodextrin and its polymer. On the other hand, adsorption affinities for bisphenol A repressed in the presence of additives. These results indicated that fine pores size of bamboo charcoals played an important role of the adsorption. The relationship between adsorption affinities and OSQR properties were also discussed in order to determine preferred adsorption behaviors of phenol and bisphenol A onto bomboo chacoals.
