| 摘 要： | 制备了一种十二烷基胍亚硫酸盐改性凹凸棒土的材料,利用红外、X射线衍射以及电镜对该材料结构进行了表征.将十二烷基胍盐改性凹土的材料用于处理含邻硝基酚的模拟废水,考察了吸附时间、pH值、邻硝基酚初始浓度以及改性凹土用量对吸附性能的影响.结果表明,在邻硝基酚初始质量浓度为100 mg/L、pH值为7、改性凹土用量为15 g/L、超声时间为40min时,邻硝基酚的去除率达到82.10%.

| Abstract: | The modified attapulgite was prepared from attapulgite and the dodecyl guanidine hydrogen sulfite ,and its configuration was characterized by IR ,XRD and SEM .The modified attapulgite was used to treat the model waste water containing 2-nitrophenol .It is studied that the impact of 2-nitrophenol original concentration ,the adsorption time ,pH of the solution and modified attapulgite addition on the adsorption capacity .The experimental results show that 2-nitrophenol removing proportion reaches 82.10% with the 2-nitrophenol concentration of 100 mg/ L ,pH of 7 ,modified attapulgite addition of 15g/L and adsorption time is 40min . |
