Characterization of uranium(VI) sorption by organobentonite
The U(VI) sorption on the bentonite modified by hexadecyltrimethylammonium bromide (HDTMA) was studied in the concentration range: 0.0001–0.001 mol/dm 3 in the aqueous phase and in the pH range: 3–10. The experiments concerning the pH influence on the molar absorption coefficient c b of U(VI) in the...
