Characterization of Strontium Adsorption from Aqueous Solutions Using Inorganic Materials Impregnated with Ionic Liquid

Abstract—New materials were obtained by impregnation of trihexyltetradecylphosphonium chloride (Cyphos IL-101) onto Florisil and Silica in order to be used as adsorbent in the removal process of Sr2+ from aqueous solutions. The obtained materials were characterized through FT-IR, SEM, EDX, and BET analysis. The adsorption process has been investigated as a function of pH, solid:liquid ratio, adsorbate concentration, contact time and temperature. The isotherm data were well described by Langmuir isotherm model. The maximum adsorption capacities was found to be 2.94 mg Sr2+ / g of adsorbent in case of Florisil and for Silica impregnated with Cyphos IL-101 is 3.97 mg Sr2+ / g of adsorbent. The results indicate that the adsorption fitted well with the pseudo-second order kinetic model.

Index Terms—Sr2+ adsorption, Cyphos IL-101, isotherm model, kinetic model.
