Fe/C-basedmagneticallyactivatedcarbon(MAC)wasobtainedbycarbonizingandactivatingitsprecursor,thatwaspreparedbyco-precipitationofanthracitecoalimpregnatedinferricchloridesolution.TheeffectoftheconcentrationsofFeCl3andpHofsolutiononBETsurfacearea,porevolumeandmagneticpropertiesoftheMACwasstudiedbyBETN2adsorptionandVSMmethod.TheresultsindicatedthatthemagnetizationofMACgraduallyincreaseswithincreasingconcentrationofFeCl3andpHvalueofsolution,andBETsurfaceareawasinclinedtofluctuation.ThelargestBETsurfaceareaandmagnetizationofMACwere1327.5m2/gand35.56emu/g,respectively.TheformofmagneticmatterinthemagneticallyactivatedcarbonwasmainlyFe3CbyX-raypowderdiffraction(XRD)andmagneticattractiontest.
