| 摘 要： | 将离子型单体丙烯酸(AA)及非离子型单体丙烯酰胺(AM)接枝在羧甲基纤维素(CMC)上,通过协同作用提高材料的吸水性及吸水速率,并研究了其对铜离子的吸附性能.通过傅里叶红外(FTIR)对材料分析表明,从及AM成功接枝在CMC上;对吸附物进行了表面分析,扫描电镜图(SEM)显示吸附物表面有大量颗粒状物质,X射线能谱(XPS)证实材料表面吸附了铜离子;在浓度为10mmol/L的铜离子溶液中,CMC-g-P(AA-co-AM)材料的吸附容量为20.30mmol/g. |
| 关 键 词： | 接枝 羧甲基纤维素 铜离子 吸附 |

| Abstract: | In this paper,acrylic acid and acrylamide were grafted on carboxymethylcellulose in order to enhance its absorbency and absorption rate;we also studied its adsorptive performance of copper ions.The structure of CMC-g-P(AA-co-AM) was studied by FTIR,the results showed that AA and AM were successfully grafted on CMC;the adsorptive structure of the material was characterized by SEM and XPS,there were many granules on its surface,the granules were proved to be copper ions by XPS,and the adsorption capacity is 20.30mmol/g when copper ion solution concentration was 10mmol/L. |
