Abstract：

The　potential　application　of　copper　coordination　polymer　with　dithiooxamide　(H2dtoaCu),　one　of　the　metal-organic　frameworks　(MOFs)　in　the　adsorption　removal　of　crystal　violet　(CV)　from　aqueous　solution　was　studied.　Batch　adsorption　experiments　were　carried　out　as　a　function　of　initial　pH,　adsorbent　concentration,　contact　time,　initial　dye　concentration　and　temperature.　The　adsorption　of　CV　on　H2dtoaCu　can　be　best　described　by　the　Langmuir　isotherm　model　(R2　>　0.9983)　with　maximum　monolayer　adsorption　capacity　of　165.83,　185.87,　and　204.50　mg　g-1　at　298,　308,　and　318　K,　respectively.　The　kinetics　of　CV　adsorption　followed　pseudo-second-order　model　(R2　>　0.9984)　and　the　chemisorption　was　proved　to　be　rate-limiting　step.　Thermodynamic　parameters,　the　change　of　free　energy　(ΔG°),　entropy　(ΔS°)　and　enthalpy　(ΔH°),　showed　that　the　adsorption　of　CV　on　H2dtoaCu　was　feasible,　spontaneous　and　endothermic　process.　Here　we　concluded　that　H2dtoaCu　is　a　promising　adsorbent　for　the　removal　of　harmful　dyes　from　aqueous　solution.　Copyright　©　2013　Wiley　Periodicals,　Inc.
