The　Fe3O4　coated　polystyrene　microsphere　(PS),　namely　Fe3O4@PS　was　firstly　fabricated　by　co-precipitation　method　with　FeCl2·6H2O　and　FeCl3　as　raw　material,　and　PS　microsphere　as　tempelate.　Then　Fe3O4@PS　was　immersed　in　toluene　solution　for　removing　the　PS　template.　Next,　the　hollow　Fe3O4　microsphere　was　coated　with　graphene　oxide　sheets　under　sonication　to　produce　the　hollow　magnetic　graphene　oxide　(HMGO).　Subsequently,　the　absorption　performance　of　the　HMGO　for　methylene　blue　(MB)　was　assessed　in　an　artificial　waste　MB　solution.　Results　verified　that　the　adsorption　process　reach　to　equilibrium　at　55　after　60　min.　The　maximum　adsorption　capacity　of　MB　on　HMGO　is　349.85　mg·g-1.　The　adsorbent　shows　good　stability　and　reusability,　after　8　times　recycling　the　adsorption　rate　is　still　higher　than　80%.　The　adsorption　process　of　MB　on　HMGO　can　be　well　fitted　by　Pseudo-second-order　kinetic　model　and　the　adsorption　rate　is　sensitive　to　the　initial　concentration.　The　adsorption　isotherm　conforms　to　the　Langmuir　isotherm　model,　and　the　adsorption　process　is　a　single-layer　surface　adsorption.　©　2021,　Editorial　Office　of　Chinese　Journal　of　Materials　Research.　All　right　reserved.
