Study on the Intercalation Organobentonite and its Adsorption

YANG Ying-qin,CHEN Hui-juan(College of Chemistry and Chemical Engineering,Xinyang Normal University,Xinyang 464000,China)  
The intercalation complex organic bentonite has been prepared by sodium bentonite.The dependence of the absorption performance on the ratio of surfactant to shell glycan and the different adding means was ivestigated.The regeneration of the intercalation complex organic bentonite was discussed.The result indecates that higher absorption efficiency was obtained under the condition of the ratio 2∶1 and two step adding.The absorption efficiency reached 96.3% at the pH 8 of the waste water,while that of the regenerated intercalation complex organic bentonite reached 95.6 %.
