磁性树脂(MINX)作为一种新型强碱型阴离子交换树脂能够通过离子交换作用去除水体中天然有机物和无机阴离子。与传统离子交换树脂相比,Mm)(回具有吸附速率快,易再生等优势,正逐渐应用于饮用水净化与深度处理领域。论文综述了MIEX的主要理化特性;在水处理中的应用效果,包括对目标污染物的去除以及受溶液pH值,温度,竞争吸附离子等的影响;阐述了MIE妒与混凝、活性炭、膜滤等常规处理工艺集成的可行性及优势;最后对MIEX和磁性树脂技术在国内饮用水处理应用过程中面临的问题提出了建议扣展望。
MIEX is a new magnetic ion exchange resin which can be used to remove nature organic matter and inorganic anions from water by ion exchange reaction. Different from traditional ion exchange resins, MIEX has the advantage of fast adsorption rate, easy to separate and simply regenerated by sodium chloride. This paper gives an overview of the physi-chemieal ability of MIEX and its application in the water treatment. The effect of pH, temperature, and inorganic anions on MIEX 's adsorption capacity is also summarized. Furthermore the combinatioa of MIEX and coagulation, active carbon or membrane filtration is also illustrated. At last, the potential application of MIEX in drinking water treatment in China is prospected.
