Computer Modeling and Laboratory Experiments to Design Sorbents for Remediating Radiologically Contaminated Soil and Water: Nanoscale Structured Surface Layers

This research illustrates the application of a combination of computer modeling and laboratory experiments to designing nanoscale structural surface layers of compositions for remediating radiologically contaminated soil and water. Natural sorbents and sorption materials with nanoscale structured surface layers of various structures are compared in terms of sorption efficiencies. Monte Carlo simulation to generate numerical calculations and chemical and physical analyses to verify the modeling predictions of the structure of metallic surface zones synthesized by ionic beams was performed. Fe, Al, and Al2O3 compositions were irradiated with Ti ions to form nanoscale structured surface layers of various structures. 90Sr and 137 KeywordsIonizing Fluxes; Radiation Factor; Materials Science; Modeling; Natural Sorbents; Nano Structured Surfaces; Synthesized Compositions; Soil Solutions Cs were used in the laboratory experiments to assess sorbent performance. The results demonstrate that using the sorbents with new structural forms of a surface produces increased efficiency in potential radionuclide sorption.
