| 摘 要： | 利用化学共沉淀方法制备了磁性多壁碳纳米管,研究了磁性多壁碳纳米管对水中蒽的吸附行为及pH值、离子强度、腐殖酸等因素的影响.结果表明,在弱酸性条件下其吸附效率最高,离子强度对吸附的影响较小,腐殖酸在低浓度时抑制蒽的吸附,高浓度腐殖酸则可以促进吸附;蒽的吸附过程符合准二级动力学方程;磁性多壁碳纳米管对蒽的吸附率超过98%,最大吸附量可达到95.2mg/g,能有效地去除水中的蒽.

| Abstract: | Multi-wall carbon nanotubes/iron oxide magnetic composite was prepared using chemical co-precipitation.The performance of using the magnetic composite to adsorption anthrancene from aqueous solution was investigated.The effect of environmental factors such as pH,ion strength,humic acid were discussed.The results demonstrate maximum adsorption of anthrancene could be reached under weak acid conditions.The ion strength had little effect on anthrancene adsorption.Inhibition of anthrancene adsorption was observ... |
