Ag掺杂磁性Zn（OH）2复合材料的制备

Preparation of Ag-doped Magnetic Zn（OH）2 Composites

通过配合物沉淀法制备了由贵金属Ag掺杂的磁性Zn(OH)2复合材料,利用扫描电子显微镜(SEM)、X射线衍射(XRD)、振动样品磁强计(VSM)对复合材料表征进行测试,并考察了在紫外光条件下复合材料对染料废水中亚甲基蓝(MB)的降解率,结果表明在光照4h时,Ag/Zn(OH)2/Fe3O4对亚甲基蓝(MB)的降解率为86.91%.

Magnetic Zn(OH) 2 composites doped with precious metal Ag were prepared by complex precipitation method. The properties of the composites were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and vibrating sample magnetometer (VSM), and the degradation rate of methylene blue (MB) in dye wastewater by composite materials under ultraviolet irradiation was investigated. The results showed that the degradation rate of methylene blue (MB) by Ag/Zn(OH)2/Fe3O4 was 86.91% at 4h irradiation.
