| 摘 要： | 研究了未改性、HNO3改性和NaOH改性桤木木屑对水中Hg2＋的吸附特性,并探讨了Hg2＋初始浓度、吸附时间和吸附温度对吸附率的影响。结果表明,在实验条件下,3种木屑对水中Hg2＋均有较好的吸附效果,吸附率可达99%以上。其中,N aOH改性木屑的吸附效果最好,平衡吸附量为3.00μg/g。结果表明,利用N aOH改性桤木木屑制备废水中Hg2＋吸附材料具有很好的应用前景。

| Abstract: | The adsorption behaviors of non-modified,HNO3-modified and NaOH-modified alder sawdust on Hg2+ in water were investigated.The effects of initial Hg2+ concentration,adsorption time,adsorption temperature on the adsorption rate were discussed.Three sawdusts had a very good adsorption effect on Hg2+ in water,and the adsorption rate can reach over 99%.The NaOH-modified sawdust had a best adsorption capability than non-modified and HNO3-modified sawdust.The equilibrium adsorption capacity on Hg2+ by NaOH-modifie... |
