The　equilibrium,　kinetics　and　thermodynamics　of　the　adsorption　of　methylene　blue(MB)　from　aqueous　solution　onto　copper　coordination　polymer　with　dithiooxamide　(H2dtoaCu),　one　of　the　metal-organic　frameworks　(MOFs),　were　investigated　in　a　batch　adsorption　system　as　a　function　of　initial　pH,　adsorbent　concentration,　contact　time,　initial　dye　concentration,　and　temperature.　The　Langmuir,　Freundlich,　and　Dubinin-Radushkevich　(D-R)　isotherm　models　were　used　for　modeling　the　adsorption　equilibrium.　It　was　found　that　Langmuir　model　yielded　a　much　better　fit　than　the　Freundlich　model　under　different　temperatures.　The　maximum　monolayer　adsorption　capacities　of　MB　were　192.98,　229.86,　and　297.38　mg/g　at　298,　308,　and　318　K,　respectively.　The　calculated　mean　adsorption　energy　(8.2611.04　kJ/mol)　using　D-R　model　indicated　that　the　adsorption　process　might　take　place　by　chemical　adsorption　mechanism.　Otherwise,　the　kinetic　studies　revealed　that　the　adsorption　process　could　be　well　explained　by　pseudo-second-order　rate　kinetics　and　intraparticle　diffusion　was　not　the　rate-limiting　step.　Thermodynamic　studies　indicated　that　this　system　was　feasible,　spontaneous,　and　endothermic　process.　Based　on　these　studies,　H2dtoaCu　can　be　considered　as　a　potential　adsorbent　for　the　removal　of　MB　from　aqueous　solution.　©　Copyright.
