Inorganic composites based on carboxymethyl cellulose: preparation, characterization, sorption, and selectivity behavior for some radionuclides from radioactive solutions

Abstract

This work is interested in the sorption and separation of 131Ba, 109Cd, 152+154Eu, and 97Zr from radioactive solutions onto barium molybdenum titanate loaded on carboxy methyl cellulose (BaMoTi@CMC) composites. In this work, different samples of BaMoTi@CMC composites were fabricated by the co-precipitation method and characterized using different analytical tools such as X-ray diffraction (XRD), attenuated total reflectance (ATR), and scanning electron microscope (SEM). The batch sorption investigations on 131Ba, 109Cd, 152+154Eu, and 97Zr include the influence of time, pH, and metal ion concentrations. The data reveal that S-3 has higher sorption efficiency than S-2 under all conditions. Isotherm is studied by Langmuir and Freundlich models. Binary systems data confirm that Cd(ii), Ba(ii), and Zr(iv) can be separated from Cd–Eu, Ba–Eu, and Zr–Eu binary systems using S-2 and S-3 at different pHs. Finally, the data prove that Zr(iv) and Ba(ii) can be easily separated from tertiary systems (Zr–Ba–Cd) onto S-2 and S-3 at pH 2.
