Abstract
Macroporous Me2-CA-BTP/SiO2-P was used for separating 241Am(III) from lanthanides. Good selectivity towards 241Am(III) was achieved in 0.1–3 M HNO3. Adsorption equilibrium of 241Am(III) was obtained within 1 h in 0.1 M HNO3 solution. 241Am(III) was efficiently separated from lanthanides through column experiment in both 0.1 M HNO3 and 0.01 M HNO3–0.34 M NaNO3 solution. It still performed excellently at 207 kGy under γ irradiation in nitrate medium. In a word, Me2-CA-BTP/SiO2-P is a very promising candidate for separating MA from Ln that even a salt-free Ln&MA separation process may be established such as from 0.1 M HNO3 based on it.
