凹凸棒石/CoFe2O4磁性复合材料对Cr(Ⅵ)的吸附性能OA北大核心CSCDCSTPCD
Adsorption capability of Cr(Ⅵ) on attapulgite/CoFe2O4 composite materials
采用低温回流法制备凹凸棒石/CoFe2O4磁性复合材料,利用比表面积(BET)、磁滞回线、红外光谱(FTIR)等手段对磁性复合材料进行表征,并研究磁性复合材料对Cr(Ⅵ)的吸附性能,利用吸附前后FTIR和光电子能谱(XPS)对其吸附机理进行初步探讨.结果表明,磁性复合材料的比表面积为175.85 m2·g-1,略大于凹凸棒石;饱和磁化强度为14emu·g-1,易于磁分离.pH在2～12范围内,吸附量随pH值的增大而减小.Freundlich等温吸…查看全部>>
A low-temperature reflow method was adopted to prepare an attapulgite/CoFe2O4 magnetic composite material.The specific surface area (BET),the magnetic hysteresis loop,and Fourier transform infrared spectroscopy (FTIR) were used to characterize the composite materials,and the adsorption properties of Cr(Ⅵ) were studied.The adsorption mechanisms were investigated using FTIR and X-ray photoelectron spectroscopy (XPS) before and after adsorption.The results show…查看全部>>
