ABSTRACT


A novel immobilized acidic ionic liquid was synthesized and characterized by FT-IR, element analysis and TGA. The immobilized ionic liquid could selectively adsorb hexavalent chromium ions (exclusive of trivalent chromium ions). The effects of important factors including adsorption time, temperature, adsorbent amount and initial concentration on removal of Cr6+ were investigated. The maximum adsorption ratio could achieve 92.12% and the adsorption amount did not have a significant reduction within at least 5 run with HCl as eluent. The adsorption equilibrium time of the immobilized ionic liquid was very short and its kinetics matched well with pseudo-second order. The adsorption isotherms were fit well to Langmuir model instead of Freundlich model.


Keywords: Immobilized Ionic Liquid, Silica, Adsorption, Thermodynamics, Chromium Ions
