| 摘要: |
| 通过用十六烷基三甲基溴化铵（简称CTMAB）改性膨润土，制得CTMAB有机土，并研究其对水体中的硝基苯的吸附效果；结果表明：对于50ml浓度为10mg/L的硝基苯水溶液，CTMAB有机土投加量为1g时，在80min左右，达到吸附平衡，对硝基苯的最大去除效率达到62.4%；PH对CTMAB有机土吸附硝基苯影响不大，对于钠化土有很大影响；CTMAB有机土对硝基苯的吸附符合Langmuir、Freundlich等温吸附模型。 |

| 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 1g/50ml of 10mg/L nitrobenzene solution,the adsorption was balanced when the adsorption time was 80 min and initial concetration of wastewater was 10mg/L,PH value little affects... |
| Key words: organic bentonite nitrobenzene adsorption removal efficiency |
