“Fabrication of Low Cost Adsorbent Nanomaterials for Efficient Removal and determination of Radionuclides from Liquid Wastes ”

Abstract

Low cost magnetic nanoadsorbents were designed and fabricated by simple, green and industrial effective method. The microstructure and morphology of the designed nanomaterials were examined via XRD, FTIR, TEM, EDX and VSM. The prepared nanocomposites were introduced as a novel adsorbent for uranium ions scavenging from aqueous solution. Different operating conditions of time, pH, initial uranium concentration, adsorbent amount and temperature were investigated. The experimental data shows a promising adsorption capacity. The kinetics and isotherms adsorption data were fitted with the pseudo-second order model and Langmuir equation, respectively. Finally, the designed nanocomposites were found to have a great degree of sustainability (above 5 times of profiteering) with a complete maintenance of their parental morphology and adsorption capacity.
