Abstract
A Promising nanocomposite from beta-Cyclodextrin/Alginate (beta-CD/Alg) composite impregnated with nickel oxide nanoparticles (NiO) has been synthesized and characterized using diverse techniques like FT-IR, XRD, TGA, and SEM. The new nanocomposite has been investigated for the efficient remediation of Cr-51 and Mn-56 radionuclides from simulated contaminated radioactive water. All the controlling experimental parameters such as solution pH, contact time, initial radionuclides concentration and adsorbent mass have been investigated and optimized. The distribution coefficient values Kd (mL/g) for Cr-51 and/or Mn-56 radionuclides have been calculated for all factors it was found that the optimum pH values were at 5 and 6 with Kd 5300, and 4500, for Cr-51 and/or Mn-56, respectively and the equilibrium was at 90 and 100 (min) with Kd values 5600 and 4800 for Cr-51 and/or Mn-56, respectively.
