Magnetic Fe-containing ordered mesoporous carbons(Fe/OMCs)with high surface area and large pore volume provide an easy and effective way for the treatment of dye in waste water.Fe/OMCs were synthesized by the soft-template route
wherein phenolic resin was used as a carbon precursor
triblock copolymer F127 as a template agent
tetraethylorsilicate(TEOS)as a silica precursor and hydrated iron nitrate as an iron source.The effects of Fe(NO3)3?9H2O loading on the morphology
structural parameters
and magnetic properties of the Fe/OMCs were evaluated by X-ray diffraction(XRD)
N2 sorption analysis
transmission electron microscopy(TEM)and physical property measurements.By using methylene blue(MB)as model dye
the adsorption of MB on the obtained Fe/OMCs was investigated.The experimental results showed that the ordering
specific surface area and total pore volume decreased with the increase of Fe(NO3)3?9H2O loading.The Fe/OMCs had fast adsorption ability for MB.The adsorption of MB on the obtained Fe/OMCs followed the Sips adsorption equation and the corresponding parameters were obtained.
