Könnecke, V. Neck, Th. FanghÄnel, J. Kim] Isopiestic vapor pressure experiments are performed at 25°C with aqueous NaTcO4, mixed NaTcO4-NaCl, and NaCl reference solutions. The solubility of CsTcO4 is determined in 0-7.4m CsCl and in 0-5.6m NaCl solutions. The osmotic coefficients of the binary and ternary solutions are used to evaluate the binary Pitzer parameters Β0, Βl, and CΦ for NaTcO4 and the mixing parameters θTcO 4 - /cl- and ψNa +/TcO 4 - /cl-. The binary Pitzer parameters for the sparingly soluble CsTcO4 and CsC1O4 are calculated together with ψCs +/mo 4 - /cl- from their solubilities in CsCl solution. The solubilities of CsTcO4 in NaCl and CsClO4 in NaClO4 solution are also included in the parametrization of the reciprocal salt systems Na+/Cs+/Cl-/MO 4 - . The parameters Β0 and Βl of pertechnetate and perchlorate salts correlate well with the ionic radii.
