Abstract
Extraction of uranyl nitrate with tri-n-butyl phosphate and diisooctyl and diisoamyl methylphosphonates in kerosene and RED-1 as diluents from aqueous solutions and extraction with diisooctyl methylphosphonate from solutions containing salting-out agents was studied. The effect of the ionic strength of the aqueous phase and extractant concentration on concentration extract ion constants was considered.
