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. |
