Abstract：

The　hydroxylation　ionic　liquid-iron　coordination　complexes　(HILICC)　with　ionic　liquid　1-butyl-3-　methylimidazolium　and　OH　groups　as　ligands　were　synthesized　and　then　were　explored　as　adsorbents　to　recover　the　reactive　blue　19　dyes　from　the　dyeing　wastewater.　The　effect　of　adsorption　time,　temperature,　dye　concentration　and　pH　on　the　adsorption　efficiency　was　investigated.　An　adsorption　efficiency　of　ca　98%　was　achieved　when　3.0　ml　of　0.05　gL-1　reactive　blue　19　dye　under　pH　for　4-5　was　adsorbed　by　0.02　g　HILICC.　The　desorption　efficiency　of　reactive　dyes　were　more　than　60%　and　recovery　efficiency　was　more　than　54%　when　the　3.0　ml　of　0.1　molL-1　NaOH　solution　was　applied　to　desorb　0.02　g　HILICC.　©,　2015,　Chemical　Industry　Press.　All　right　reserved.
