摘要
Abstract
The removal effect of nitrobenzene in the aqueous solution is studied by using the oganic bentonite modified by CTMAB. The results show that the best removal efficiency of nitrobenzene was up to 62.4% ,while the modified organic bentonite addtion amount was 1 g/50 mL of 10 mg/L nitrobenzene solution, the adsorption was balanced when the adsorption time was 80 min and initial coneetration of wastewater was 10 mg/L. pH value little affects the adsorption of nitrobenzene by CTMAB- bentonite, the influence of pH on the adsorption of nitrobenzene by CTMAB organic bentonite is small but is big by Na - bentonite. Adosrption isotherms of nitrobenzene is in accordance with Freundlich and Langmuir isothermal adsorption model.关键词
