| Abstract: | ![]()
The sorption of uranium from aqueous solutions on titanium and zirconium phosphates in H+ and K+ forms modified by iron or aluminum ions has been investigated. The modified pattern of porosity is much better, than for none modified analogous, owing to their increased sorption capacity and kinetics of uranium absorption. The modified sorbents display selectivity towards uranium, that allows to purify solutions up to the content of uranium below the limit of its analytical definition. |
