A new high-swelling multi-component superabsorbent composite Na-CMC-g-P(AMPS-co-AA-co-AM)/NanoFe₃O₄ (SANCHs) was successfully designed and utilized for effective removal of ¹³⁴Cs, ⁸⁵Sr and ⁶⁰Co radionuclides from radioactive wastewater. The structure and morphology of the superabsorbent composite have been mapped and characterized using different techniques (SEM, XRD, TEM, FTIR, and TGA). Superabsorbent hydrogel composite networks with magnetic iron particles have been disclosed to provide an advantage over previous methods. By using distinct models for kinetic investigation, mathematical fitting was observed to be pseudo-second-order with (R²) 0.987, 0.999, and 0.998 respectively for ¹³⁴Cs, ⁶⁰Co, and ⁸⁵Sr. In addition, the highest adsorption capability was found to be 23.9, 43, and 47.2 mg g⁻¹ respectively. The variation in the magnitude of enthalpy (ΔH) and free energy (ΔG) verify the spontaneous state of the adsorption reaction suggesting an endothermic process. Such a functionalized magnetic nanocomposite adsorbent demonstrates excellent prospective applications for effective separation of certain radionuclides from radioactive liquid waste.
