Abstract—The paper presents the studies regarding the impregnation of Florisil with Cyphos IL-101 using a new method of impregnation instead of the classic methods: the ultrasonication. In order to determine the efficiency of the ultrasonication methods of impregnation, the work conditions were varied, and the obtained supported ionic liquids were characterized through scanning electron microscopy (SEM), energy dispersive XRay analysis (EDX) and FTIR- Fourier transform infrared spectroscopy. From the experimental data was observed that only the amplitude of ultrasonication had a significant influence onto the impregnation process efficiency. The impregnated material obtained in the optimum conditions showed good adsorption performance in the removal process of Cs+ developing a maximum adsorption capacity of 2.95 mg/g.
Index Terms—Ultrasonication, impregnation, ionic liquid, Cs+ adsorption.
