摘　　要：以Fe3O4微粒作为载体,糠醛单体为主要原料通过酸催化聚合-热处理的方法制备了磁性功能高分子PFD/Fe3O4光催化材料.采用透射电子显微镜(TEM)、X-射线衍射(XRD)、红外光谱(IR)、热重分析(TG-DTA)以及紫外-可见光谱(UV-Vis)等技术对样品的形貌、结构、光吸收特性等进行了表征.以亚甲基蓝溶液的脱色降解为模型反应,考察了样品的光催化性能.结果表明,在自然光照射下,反应40min后,PFD/Fe3O4对亚甲基蓝溶液的脱色率达到85%左右,COD去除率为47.37%.PFD/ Fe3O4 magnetic functional polymer materials were successfully prepared via acid-catalyzed heat-treated process using furfuryldehyde monomer and Fe3O4 powder. TEM,XRD,IR,TG-DTA and UV-Vis techniques were employed to characterize the morphology,surface structure,and optical absorption properties of the sample. Photocatalytic degradation performance was investigated using methylene blue pollutant. The results showed that the decolorizing efficiency of the MB solution reached about 85% at radiation time of 40 min and mineralizing efficiency was 47.37%.
