随着工业化和城市化的快速发展,重金属污染己成为不容忽视的环境问题[1].重金属在自然环境中很难被降解,并且可以在生物体内累积和转化,通过食物链的作用不断富集,对食品安全、生态平衡及人体健康产生重大威胁.因此,开发高效、低成本的重金属废水深度处理技术不仅是环境工程领域面临的难题,也是国家的重要需求.本文通过偶联-预聚工艺,使无机y-Fe203均匀混入油相中,然后进行聚合反应和水解反应制备出不同y-Fe203磁粉含量的磁性弱酸树脂。通过表征了解磁性树脂的表面形貌和磁力特征,研究了其对Cu2+、Ni2+的吸附性能,并考察了树脂的抗酸性能及再生稳定性。

互贯聚合物网络由两种或多种互相贯穿的交联聚合物组成的共混物,其特点是通过化学交联施加强迫互容作用使聚合物链互相缠结,形成相互贯穿的交联聚合物网络,达到抑制热力学上相分离的目的,增加两种组分间的相容性形成比较精细的共混物结构.由于其独特的结构形态,互贯聚合物网络应用于离子交换与吸附树脂,可以形成性能互补的双网结构,在吸附分离领域具有广阔的应用前景.
