可回收Fe3O4@SiO2-Ag磁性纳米微球对染料污染物的快速脱色处理
DOI: 10.1016/S1872-2067(12)60605-6, PP. 1378-1385
Keywords: 四氧化三铁纳米颗粒,催还还原,染料,可回收催化剂
Abstract:
？介绍了一种采用无毒廉价的前驱物制备Fe3O4@SiO2-Ag磁性纳米微球的快捷方法,制备的Fe3O4@SiO2-Ag纳米微球在NaBH4存在下可以催化还原染料污染物.实验结果表明,Fe3O4@SiO2-Ag磁性纳米粒子保持了Ag纳米粒子和Fe3O4纳米粒子的双重优点,不仅对染料罗丹明B和曙红Y具有良好的催化还原效率,而且可以在外加磁场作用下从溶液中快速有效的分离.催化还原反应速率与反应温度及Fe3O4@SiO2-Ag催化剂用量有关,反应体系中表面活性剂和无机盐(Na2SO4)的存在也会影响催化剂的催化活性.该Fe3O4@SiO2-Ag磁性纳米粒子在工业染料污染物处理方面具有应用前景.
