Description

Extraction of perrhenic acid in the absence and presence of sodium salts (NaCl, NaNO3) is studied using rhenium-186, 188. Distribution coefficients of perrhenic acid grow with the increase of rhenium (7) concentration in the aqueous phase, this being connected with acid polymerization in the organic phase as a result of hydrogen bond formation. Perrhenic acid and its salt are extracted in the presence of NaCl or NaNO3. That is why, rhenium (7) distribution coefficient dependence curves have minimums. Existence of minimums is conditioned by the superposition of two processes- NaReO4 dissociation and HReO4 association in the organic phase
