磁性响应茶渣制备及其对水溶液中亚甲基蓝的吸附
|
摘要
采用化学共沉淀技术制备了茶渣(TW)/纳米Fe_3O_4磁性复合材料(magnetic tea waste,MTW),用扫描电镜(SEM)、X射线光电子能谱仪(XPS)、傅里叶变换红外光谱仪(FTIR)、X射线粉末衍射仪(XRD)和比表面积测定仪(BET)对其结构进行了表征,并考察了其对水溶液中亚甲基蓝(methylene blue,MB)的吸附性能。结果表明,MTW磁性响应明显,其表面可见有颗粒状物质堆积。MTW对MB吸附量随Fe_3O_4负载量增加而先增大后减小,并在负载量为23.16%时达到最大,此时MTW表面Fe元素的原子分数为5.24%,比表面积比TW增大85.71%,孔容积增大1倍。在303K下其对MB的Langmuir最大吸附量为160.5mg/g,比TW提高了9.93%,并具有良好的再生与循环使用性能。
Tea waste/nano-Fe_3O_4 magnetic composited adsorbent(MTW) was prepared by co-precipitation approach and characterized by scanning electron microscope(SEM), X-ray photoelectron spectroscopy(XPS),Fourier transform infrared(FTIR), X-ray diffraction(XRD), and surface area measurement. The adsorptionproperties of the methylene blue(MB) from aqueous solution onto the MTW was also studied. The resultsshowed that the MTW was successfully synthesized, which provided a good magnetic response. Thesurface of MTW was full of particulate matter deposited and showed a rough morphology. The adsorptioncapacity of MB onto MTW increased first then decreased with the increment in nano Fe_3O_4 content, andreached the maximum with 23.12wt% of nano Fe_3O_4. The content of Fe distributed on the surface of MTWwith 23.16% content of nano Fe_3O_4 was at 5.24%. The specific surface area of the MTW was increased by85.71% when compared with TW. The saturated adsorption capacities of MB onto MTW was 160.5mg/g at 303K,which was higher than TW by 9.93%.The adsorbent showed a satisfactory regeneration and recycling utilization performances.
