摘要
固体Fenton催化剂由于其可回收性,清洁无污染等特点受到广泛的关注。本文利用γ射线辐照制备Fe3O4磁性材料,并研究了不同辐照剂量所制备的Fe3O4对罗丹明B(RhB)染料的去除效率,最后得出使用辐照剂量为5KGy所制备的磁性材料在pH为3,温度55℃的条件下只需16min就可将RhB染料完全降解。
Solid Fenton catalyst has attracted wide attention because of its recyclability,clean and pollution-free.Fe3O4magnetic materials were prepared byγradiation irradiation,and the removal efficiency of rhodamine B(RhB)dyes by the Fe3O4prepared with different irradiation doses was studied.The results show that the magnetic material prepared with irradiation dose of 5 KGy can completely degrade the RhB dye under the condition of pH of 3 and temperature of 55℃.
