摘要:
采用超声辅助反向共沉淀法制备了高活性的Fe3O4磁性纳米颗粒（Fe3O4 MNPs）.采用XRD,FTIR和Raman等仪器对Fe3O4 MNPs的组成、结构进行了表征和研究.以Fe3O4 MNPs为类酶催化剂,Na2S2O8为氧化剂,在室温25 ℃的条件下,降解对硝基酚的优化条件为:10 mg·L-1对硝基酚溶液,在pH=3.8,Fe3O4 MNPs用量为0.9 g·L-1,Na2S2O8用量为6.3 mmol·L-1时,无需超声、紫外光照和Gamma辐射的条件下,30 min后其降解率达到97%以上.
Abstract:
Fe3O4 magnetic nanoparticles (Fe3O4 MNPs) with highlyefficient were successfully prepared through an advanced reverse coprecipitation method under the assistance of ultrasound irradiation. The structure and morphology were characterized by Xray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and Raman spectroscopy. Removal of pNitrophenol (pNP) pollutant was investigated by using Na2S2O8 as an oxidant and Fe3O4 magnetic nanoparticles (MNPs) as a peroxidase mimetic in a wide pH range from 2.0 to 10.0 at 25 ℃. It was found that Na2S2O8 (6.3 mmol·L-1) was activated by 0.9 g·L-1 Fe3O4 MNPs at pH 3.8 and removing of 10 mg·L-1 pNP was above 97% in 30 min, without heat or ultrasoundassisted or UV or Gamma irradiation.
