| 摘 要： | 以稻草秸秆为原料,用多种胺基试剂经氯化和胺化反应对稻草秸秆进行改性,制成多种改性胺基稻草纤维并用于电镀废水中重金属离子Fe3+、Ni2+、Cu2+、Zn2+的吸附,并用扫描电子显微镜、X射线衍射仪等分析手段对改性纤维的表面形貌和结构性能进行了表征。实验结果表明:乙二胺基稻草纤维吸附Fe3+、Ni2+、Cu2+、Zn2+性能明显优于稻草纤维原料和其他胺基改性稻草纤维;胺基改性稻草纤维对金属离子吸附能力与含氮量有一定相关性;乙二胺基稻草纤维吸附电镀废液中Fe、Ni、Cu、Zn效果明显。 |

| Abstract: | The rice straw stalk is used as raw material for preparation of many modified amino fibers via chlorination and aminating.The modified amino rice straw fibers are used for absorbing the heavy metal ions(Fe3+,Ni2+,Cu2+ and Zn2+) in plating wastewater.The surface morphology and the structure of modified fibers are characterized by SEM and XRD.The results show that the ethylenediamine-based straw fiber has good adsorb ability of Fe3+,Ni2+,Cu2+ and Zn2+ in plating wastewater compared with the straw fiber raw ma... |
| Keywords: | rice straw stalk modified fiber plating wastewater heavy metal ions |
