Due to the hazard bringing to human, Bisphenol A pollution problem has drawn more and more attention in water treatment field. This study has developed a kind of modified zeolite as absorbent to remove it. Natural zeolite and chitosan were adopted in experiments. Results indicated that the modified zeolite bore more pore volumn and specific area than natural zeolite. To modified zeolite, natural zeolite and chitosan the adsorption of bisphenol was finished in 6-8h. Modified zeolite showed relatively excellent adsoptive capicity in batch and column experiments. The Freundlich isotherm was suitable in describing the sorption behaviour. Organic matters in water might be an important factor to debase the adsorption. To practice application velocity of 4.2-6.1 m·h-1 was suitable and the form of several column connected in serious was recommended.
