Sorption of Aniline and Phenol to Anioncation Organobentonites from Water
|
Abstract:
A series of anioncation organobentonites were synthesized by covering anioncation mixed surfactants on the bentonite.The intelayer spacings and organic carbon contents of anioncation organobentonites were analyzed.The sorption properties,mechanisms and optimal conditions of organic compounds to anioncation organobentonite were discussed.The results indicate that the organic carbon contents of anioncation organobentonites are proportional to the amounts of anion and cation surfactants covering onto bentonite.Partition medium are excellently created in anioncation organobentonites for organic pollutants in water.The sorption properties of anioncation organobentonites are fine when the alkychain of anion surfactant is same as of cation surfactants exchanging on bentonite.Removal rates of organic pollutants from water are improved by synergistic solubilization of anion and cation surfactant on the organobentonites.
