Abstract
Selected extraction systems of TcO4--(H,Na)A-H2O/R(TcO4,A)-CHCl3, C6H5 NO2 type, where A = Cl-, NO3-, ClO4-, R = (C6H5)(4)As+, were studied. The solvent extraction of sub- and super-stoichiometric ratio of Tc:R was performed. The solubility of (C6H5)(4)AsTcO4 in water, chloroform and nitrobenzene were determined too. The results of the extractions a re presented in the form of TcO4- distribution dependencies on the pha se composition and the extraction constants of individual TcO4-, Cl-, NO3-, ClO4- anions and TcO4--Cl-, TcO4--NO3-, TcO4--ClO4- ion pairs.
