In　this　paper,　the　effect　of　cyanoguanidine　(CNGE)　for　tailoring　pore　size　during　the　soft-templating　preparation　of　mesoporous　carbon　materials　was　studied.　In　consideration　of　cyclic　utilization,　the　surface　of　the　mesoporous　carbon　materials　were　doped　with　magnetic　Fe3O4　particles.　The　characterization　results　(including　TEM,　XRD,　BET,　TGA　and　FT-IR)　showed　that　adding　CNGE　did　not　destroy　the　ordered　porous　structure;　instead,　it　changed　the　pore　size　from　2.98　nm　to　9.42　nm.　Besides,　the　mesoporous　carbon　materials　exhibited　a　strong　magnetic　response　owing　to　the　dopant　of　Fe3O4　particles.　With　the　increase　in　CNGE,　some　functional　groups　were　added　to　the　surface　of　the　mesoporous　carbon　materials,　which　partly　promoted　the　adsorption　effect.　The　results　indicated　that　adsorption　approached　equilibrium　in　the　first　10　min　and　reached　the　maximum　when　the　pore　size　was　5.89　nm.　The　kinetic　of　minocycline　adsorption　on　magnetic　ordered　mesoporous　carbon　material　could　be　interpreted　by　a　pseudo-first-order　model.　The　adsorption　isotherms　showed　that　the　adsorption　process　was　complex,　combining　physical　and　weak　chemical　adsorption,　in　good　agreement　with　the　Sips　model.
