摘　　要：对比分析了自主研发、生产的国产丙烯酸系磁性阴离子交换树脂(CMIET)和进口树脂(MIEX)的结构、性能及工业化应用效果。结果表明,两者均以γ-Fe_(2)O_(3)作为磁性材料,具有铁磁性和自吸沉降性能。两者同样具有微孔结构,CMIET的表面有丰富的孔洞,结构粗糙,可提供更多的吸附位点;CMIET在去除单宁酸(TA)和无机阴离子PO_(4)^(3-)、NO_(3)^(-)方面优于MIEX。两种树脂在应用前后磁性和粒径变化均不大。在同等水质情况下,两者均能够在水处理系统中形成稳定的床层,CMIET在去除可溶性有机碳(DOC)方面优于MIEX。总之,CMIET呈现出具有较好结构性能和较低运行成本的双重优势。The structure,performance,and industrial application effect of domestically produced acrylic acid magnetic anion exchange resin(CMIET)were compared and analyzed against those of imported acrylic acid magnetic anion exchange resin(MIEX).Both resins utilizing γ-Fe_(2)O_(3) as the magnetic component exhibited ferromagnetic properties and self-adsorption sedimentation characteristics.Both resins possessed a microporous structure.However,the surface of CMIET exhibited a porous and rough morphology,providing abundant adsorption sites.Additionally,CMIET demonstrated superior performance compared to MIEX in the removal of tannic acid(TA)as well as inorganic anions such as PO_(4)^(3-)and NO_(3)^(-).The magnetic properties and particle size of the two resins exhibited minimal change before and after application.In industrial operations with identical water quality conditions,both resins were capable of forming stable bed layers within the water treatment system.However,CMIET demonstrated superior performance compared to MIEX in terms of dissolved organic carbon(DOC)removal.In summary,CMIET offers dual advantages of superior structural performance and reduced operating costs.
