辣木籽壳对亚甲基蓝的吸附特性
|
摘要
以辣木籽壳作为吸附剂,考察了吸附时间、颗粒大小、温度、溶液初始浓度和pH对其吸附亚甲基蓝的影响;采用吸附等温模型和动力学模型对数据进行拟合;通过扫描电镜和红外光谱进行表征。结果表明:在辣木籽壳加入量为10g/L时,最佳吸附条件为吸附时间1.5h,颗粒大小>80目,温度25℃,亚甲基蓝溶液浓度200mg/L,pH>5;吸附过程符合Langmuir模型和准二级动力学模型,最大理论饱和吸附量为94.25mg/g;吸附过程为物理吸附和化学吸附共同作用的结果,以物理吸附为主。
Used moringa seed shell as adsorbent,investigated the effects of adsorption time,particle size,temperature,initial concentration of solution and pH on the adsorption of methylene blue.Datas were fitted by adsorption isotherm model and kinetic model.The samples were characterized by scanning electron microscopy and infrared spectroscopy.The results showed that under the condition of adding 10 g/L of moringa seed shell,the optimum adsorption conditions were adsorption time 1.5 h,particle size>80 mesh,temperature 25 ℃,methylene blue solution concentration 200 mg/L and pH>5.The adsorption process followed the Langmuir model and the pseudo-second-order kinetic model.The maximum theoretical saturated adsorption capacity was 94.25 mg/g.The adsorption process was a common result of physical adsorption and chemisorption,and mainly by physical adsorption.
