摘要： 通过碱化、环氧化、胺化等反应制备了 3种氨基木粉,进行了红外光谱和元素含量分析,并讨论了各种因素对环氧值、氨基含量的影响,同时,还考察了它们对Cu2+的吸附性能。试验表明:该类木粉具有吸附容量高、吸附速度快、易解吸、重复使用性能好的特点,可作为一种阴离子交换剂使用

关键词: 氨基木粉, 阴离子交换剂

Abstract: A series of amino woodpowder were prepared by chemical modification of wood through alkalization, epoxidation and amination.In this paper, factors affecting epoxide value and content of-NH2 were discussed, and the modified wood was tested by FT-IR and element analysis.The adsorption capacity of these samples were also studied.The result shows that three kinds of these modified woodpowders can be used as anion exchange resin.

Key words: amino-woodpowder, anion exchanger
