Extraction of moderate oxidation state technetium species between 30 % tri-n-butyl phosphate and H(2)SO(4)/HNO(3)

The extraction of technetium species at oxidation state lower than +7 has been examined in sulfuric and sulfuric/nitric acid solutions using UV–Vis spectroscopy and optically transparent thin layer cell (RVC-OTTLE). Soluble Tc(III), TcO(2+) and [Tc(2)O(2)](3+) species with absorption bands at 420–45...

description The extraction of technetium species at oxidation state lower than +7 has been examined in sulfuric and sulfuric/nitric acid solutions using UV–Vis spectroscopy and optically transparent thin layer cell (RVC-OTTLE). Soluble Tc(III), TcO(2+) and [Tc(2)O(2)](3+) species with absorption bands at 420–450, 400, and 502 nm, respectively, were detected as products of pertechnetates electroreduction. The distribution ratios of (99)Tc with lower than +VII oxidation state ionic species between 4 M H(2)SO(4) and 30 % TBP/kerosene were found and are significantly lower than for TcO(4)(−) in the same solution.
