Separation of Technetium (VII) from other Elements by Extraction with Nitrobenzene Solution of Rhodamine-B Hydrochloride

Inorganic and Nuclear Chemistry Laboratory, Institute of Science, Madame Cama Road, Bombay-32 Manuscript received 12 October 1974; revised 10 February 1975; accepted 7 March 1975 The extraction of technetium (VII) with rhodamine-B; hydrochloride into organic solvents has been investigated. Nitrobenzene, which is the most effective extractant for Tc(VII) is used to separate Tc(VII) from other elements. It has been found that Tc(VII) is extracted as ion pairs
