摘要:
以铁氰化钾、三水硝酸铜为前驱体,采用共沉淀法制得中间产物,将中间产物置于马弗炉煅烧,得到CuO/Fe3O4磁性纳米颗粒。利用X射线衍射仪、扫描电子显微镜、X-射线光电子能谱仪对催化剂进行物相、形貌和表面元素的表征。选择罗丹明B(RhB)等多种染料为目标污染物,建立的氧化体系在10 min内可以完全降解体系中的RhB(体系条件:30 ℃,CuO/Fe3O4 0.3 g/L,PMS 0.4 mmol/L,RhB 30 μmol/L,初始pH=8.0)。实验结果表明制备的CuO/Fe3O4可以高效地活化过一硫酸盐降解RhB。
Abstract:
The CuO/Fe3O4 magnetic nanocomposites were synthesized by calcining intermediate products prepared using co-precipitation of potassium ferricyanide and copper(ii) nitrate hydrate as precursors. The phases,morphologies and surface elements were characterized by X-ray diffraction,scanning electron microscopy and X-ray photoelectron spectroscopy. Rhodamine B(RhB) and other dyes were chosen as target pollutants. The established oxidation system could completely degrade RhB in 10 min with 0.3 g/L of CuO/Fe3O4,0.4 mmol/L of peroxymonosulfate and 30 μmol/L of RhB at 30 ℃ and 8.0 initial pH. Experimental results showed that RhB could be efficiently degraded by CuO/Fe3O4 activated peroxymonosulfate.
