Abstract

Abstract: Magnetic ion exchange resin (MIER) was successfully prepared using styrene type strongly alkaline ion exchange resin as matrix and with the method of co-precipitation. The surface morphology, magnetic component and magnetic property of MIER were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and vibrating sample magnetometer (VSM). The effects of adsorption time, temperature, pH and competitive ions on the adsorption performance of MIER to Cl^- in waste water were studied. The results showed that the MIER's surface was rough, the magnetic component was Fe₃O₄, and the saturation magnetization was about 2.23emu/g. Adsorption time, temperature and pH all had great influence on the adsorption performance. When the adsorption time was 3h, temperature was 30℃, and pH=3, the saturated adsorption capacity of MIER could reach 140.43mg/g. The anti-interference ability and the adsorption selectivity to Cl^- were enhanced in the wastewater containing competing ions such as SO₄^2- or NO₃^-.

摘要： 采用共沉淀法，以苯乙烯型强碱性离子交换树脂为基体，成功制备了磁性离子交换树脂。分别采用扫描电子显微镜（SEM）、X射线衍射（XRD）和振动样品磁强计（VSM）对磁性离子交换树脂的表观形貌、磁性组分和磁性能进行了表征。研究了吸附时间、温度、pH和竞争离子4个因素对磁性离子交换树脂吸附废水中Cl^–性能的影响。结果表明：磁性离子交换树脂表面粗糙，磁性组分为Fe₃O₄，比饱和磁化强度为2.23emu/g，具有超顺磁性。吸附时间、温度和pH对磁性离子交换树脂吸附Cl^–的影响较大，当吸附时间为3h、温度为30℃、pH=3时，磁性离子交换树脂的吸附量最大，达到140.43mg/g；当废水中含有SO₄^2–或NO₃^–等竞争离子时，磁性离子交换树脂的抗干扰能力增强，对Cl^–的吸附选择性也有所提高。
