| Abstract: | The adsorption behavior of organo bentonite to benzene/toluene/ethylbenzene/xylene(BTEX) and chromate in water was examined. The adsorption curves of organo bentonite for BTEX were well linear in range of 0 g/L to 0 2 g/L. The adsorption isotherm for chromate was agreed with Langmuir equation. The saturation adsorption capacity of organo bentonite to chromate was 571 21 mg/kg . Both adsorption quantities of organo bentonite to BTEX and chromate were found to be greatly increased in comparision with that of natural bentonite. The regeneration of chromate saturated organo bentonite was studied. The efficiency for extracting chromate from chromate saturated organo bentonite in alkaline solution was 84%. |
