【摘要】 以纤维素为原料，采用共沉淀法将Fe₃O₄粒子负载于纤维素中，然后用甲基丙烯酸缩水甘油酯与磁性纤维素进行接枝共聚，再与聚乙烯亚胺进行胺化反应，制得Fe₃O₄-Cell-PGMA-PEI，采用FT-IR、EA、XPS、TGA等方法对磁性吸附剂进行结构表征。在静态条件下，研究吸附剂用量、吸附时间、溶液初始p H、温度等因素对Fe₃O₄-Cell-PGMA-PEI吸附Pb²⁺效果的影响，确定吸附的最佳条件。更多还原

【Abstract】 Using cellulose as raw material,Fe₃O₄ particles were loaded into cellulose by coprecipitation method,then the magnetic cellulose was grafted with glycidyl methacrylate （GMA）,and aminated with polyethylene imine （PEI） to prepare Fe₃O₄-Cell PGMA-PEI,its structure was characterized by FT-IR,FT-IR,EA,XPS,TG/DTG.Under static condition,the effects of the dosage of adsorbent,adsorption time,initial p H and temperature on the adsorption of Pb²⁺by Fe₃O₄-Cell-PGMA-PEI were studied,and the best adsorption conditions were determined.更多还原
