INVESTIGATION OF THE PROCESS OF boric acid EXTRACTION by tributyl phosphate
Equilibrium concentrations of boric acid in the aqueous and organic phases during extraction from an aqueous solution H <sub>3</sub>BO <sub>3</sub> with tributyl phosphate (TBF) at (292 - 295) K were measured. The values of the distribution factor of boric acid for several values of the ratio of the organic and aqueous phases (O:W) obtained. It is shown that the value of the distribution factor within the accuracy of its determination does not depend on the ratio of O:W but it depends on the initial concentration of boric acid.
