| Abstract: | Different aliphatic alcohols were tested for the extraction of boric acid from solutions modeling radioactive waste. In addition to distribution measurements, the number of molecules of extractant per H3BO3 molecule in the organic phase was determined assuming extraction by solvation. A method of activity coefficient evaluation in aliphatic alcohols-nonpolar solvent systems is proposed and hydration and solvation effects in these systems are investigated. |
