| Abstract: | The preparation and characterization of ionic liquid bonded silica gel and its application in adsorption of heavy metals are introduced. Two ionic liquids bonded silica gels are prepared by bonding 1-methylimidazole and 1-ethylimidazole on silica gel with chloropropylsilane, the two kinds of silica gels are used to adsorb dichromate ions, and the adsorption behavior is analyzed theoretically. These experimental conditions are simple, and the reagents are easy to obtain. It involves the preparation of polymer materials, structural characterization, static adsorption, quantum chemistry calculation and other aspects, which is helpful to improve students’ comprehensive application of knowledge and research ability combining theory with practice. |
