采用酸碱法提取出植物纤维素,对其改性后的纤维素进行苯胺吸附实验研究,分别考察了纤维素来源、吸附剂的用量、接触时间、溶液pH值对改性纤维素的吸附性能的影响。结果表明,采用玉米秸秆制的改性纤维素吸附效果最好,在30℃下,当吸附时间30 min,pH值为7时苯胺的吸附效果最好。
Plant cellulose were extracted by acid-base extraction,and the experiment study on adsorption properties of aniline with modified cellulose are made.The adsorption effects such as the sourse of fibre,the amount of adsorbent,time,pH were evaluated by experiments.The results showed that the modified corn cellulose had higher adsorption capacities,at 30 ℃,under the condition of the adsorption time 30 min,pH = 7,the adsorption capacities of modified corn cellulose was best.
