Abstract Organic contaminants such as phenolic compounds and chlorinated compounds become serious problem threatening human health and ecosystem integrity. Simple and effective methods are presented here to prepare adsorbents by cross-linking cyclodextrin with diglycidyl ether and branched polyethyleneimine for the removal of organic contaminants in water. The cross-linked cyclodextrin hydrogels are capable of adsorbing organic contaminants by forming the inclusion complex. The properties of cross-linked cyclodextrin were characterized via FT-IR, N2 adsorption-desorption analysis, FE-SEM. The adsorption properties of cross-linked cyclodextrin for bisphenol A as a model compound were measured by UV-vis. spectroscopy. Therefore, these results suggest that the cross-linked cyclodextrin has a great potential for efficient adsorbent for the removal of organic contaminants in water.
