摘要:

采用具有单分散性、 平均粒径分别为(200±0.5) nm和(6.5±0.5) nm的Fe3O4纳米微球和CuFeS2纳米晶与生物质废弃物复合制备出Fe3O4/CuFeS2/生物质复合降解柱. 该降解柱能高效处理有机染料亚甲基蓝(MB)和罗丹明B(RhB), 降解率超过90%. CuFeS2中的Cu+能显著促进芬顿反应, 而Fe3O4较强的磁性有利于催化剂的回收. 更重要的是, 再生后的复合柱对有机染料的降解率没有明显降低, 仍可达90%以上. 此外, 该降解柱可充分利用生物质废弃物, 解决其回收利用的难题.

Abstract:

Monodispersed Fe3O4 nanospheres with diameters of (200±0.5) nm and CuFeS2 nanocrystals with diameters of (6.5±0.5) nm were mixed with biomass wastes to prepare Fe3O4/CuFeS2/biomass composite degradation column. The composite degradation column can effectively degradate organic dyes[methylene blue(MB) and rhodamine B(RhB)] aqueous solutions with degradation rates over 90%. Compared with other Fenton systems, Cu+ in CuFeS2 enormously contributes to the Fenton process. At the same time, the magne-tism of the sample can make it easy to recover. More importantly, the degradation rates after regeneration can remain over 90%. Besides, the composite can make full use of biomass wastes.

Key words: Composite dgradation column, Organic dye, Regeneration, Fenton system
