| Abstract: | The intercalation bentonite nanocomposites have been prepared by the intercalation of carboxymethyl chitosan in sodium bentonite. Their surface property, structure organization and crystal structure were determined by IR, SEM and XRD, respectively. The results showed that the N,O-carboxymethyl chitosan has been successfully inserted into the inter layers of bentonite, and as a result, the stripped nanophase compound materials were formed. The prepared materials were applied to the treatment of the waste wat... |
