Abstract

Sorption of americium from nitric acid, neutral, and alkaline solutions onto commercial samples of detonation nanodiamonds (NDs) was studied. The sorption kinetics and the dependence of the degree of sorption on pH, ionic strength, m/V ratio, and temperature were examined. Thermodynamic parameters of americium adsorption onto NDs were determined. Conditions of quantitative sorption of americium onto ND samples were found. NDs are promising sorbents for decontamination of natural waters from possible americium impurities.
