摘要
在实验室条件下,对赤泥改性进行了研究,采用了7种改性工艺,研究结果显示3号赤泥制备吸附剂效果显著。制备工艺为赤泥600℃焙烧1 h+3 mol/L HCl酸浸3 h,滤渣用碳酸钠扩孔处理,经过改性后赤泥比表面积由原来的144.7 m2/g提高到532.8 m2/g。此外还采用扫描电镜对处理样品表面进行了表征分析。
Under laboratory conditions,the red mud modification is studied,in which 7 kinds of modified processes are used and the results show that the third adsorbent prepared from red mud is obviously effective. The conditions producing adsorbent are determined： the red mud is roasted in 600 ℃ for 1 hour,then immersed in 3 mol / L HCl for 3 hours at normal temperature,and finally treated with sodium carbonate. After modified,the red mud specific surface area is increased from 144. 7 m^2/ g to 532. 8 m^2/ g. SEM is used to characterize the surface properties of the modified samples.
