Distribution coefficients for lanthanum, neodymium, yttrium, and ytterbium nitrate extraction by di- and tributyl phosphate were compared, and their relation to the concentratlon of nitric acid and nitrates in aqueous solu tion was determined. In DBP extraction an increase of nitric acid concentration and of rare-earth nitrates diminishes the distribution coefficients while in TBP extraction distribution coefficients increase with the increase of rareearth nitrate concentration. The distribution coefficients are always higher in DBP extraction than in TBP. DBP extraction at low acidity achieves better separation of rare earths than TBP; at high acidity the difference is much smaller. (R.V.J.)
