ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Isotopes & Radiation
Members are devoted to applying nuclear science and engineering technologies involving isotopes, radiation applications, and associated equipment in scientific research, development, and industrial processes. Their interests lie primarily in education, industrial uses, biology, medicine, and health physics. Division committees include Analytical Applications of Isotopes and Radiation, Biology and Medicine, Radiation Applications, Radiation Sources and Detection, and Thermal Power Sources.

2,6-bis(5,6-dipropyl-1,2,4-triazin-3-yl)pyridine (n-Pr-BTP) was impregnated on XAD-7 resin and the extraction performance of this n-Pr-BTP/XAD-7 resin was investigated for the uptake of Am(III) from acidic nitrate solutions. The uptake behavior of the lanthanides, La(III), Ce(III), Nd(III), Eu(III), and Gd(III), as well as elements such as Ba(II), Fe(III), Mo(VI), Ru(III), Zr(IV), Cs(I), and Sr(II) was also studied in batch experiments. It was found that the resin exhibited significantly high extraction and selectivity for Am(III) over the lanthanides and other elements. Based on the results obtained from batch studies, the separation behavior of Am(III) from Eu(III) was examined by extraction chromatography using a column packed with the n-Pr-BTP/XAD-7 resin. A complete separation between Am(III) and Eu(III) was achieved from aqueous phase containing nitric acid and ammonium nitrate in the column experiment. Based on this result, experiments were performed to investigate the separation of Am(III) from the lanthanides from octyl(phenyl)-N,N-diisobutylcarbamoylmethyl phosphine oxide (CMPO)-treated high-level waste.
