Sorption Properties of Sodium and Potassium Aluminosilicates from Alkaline Hydrolyzates of Rice Straw

Sodium and potassium aluminosilicates samples are synthesized from solutions formed via the alkaline hydrolysis of rice straw. The fabricated samples are characterized by means of X-ray diffraction analysis and IR-spectroscopy, and their elemental composition, particle morphology, specific surface area, and thermal properties are determined. The sorption properties of the synthesized aluminosilicates with respect to Cs + ions are investigated under static conditions. Kinetic curves and sorption isotherms are provided and a sorption kinetic model is described.
