摘要：

The activity coefficients of sodium bromide in the ternary system NaBr + NaClO4 + H2O were determined at 25 degrees C and constant ionic strength of 0.1, 0.5, 1, 2, and 3 mol-kg(-1) from emf of the cell without liquid junction ISE-Na \ NaBr(m(A)), NaClO4(m(B)), AgCl(S) \ Ag The experimental activity coefficients were comparatively analyzed by using the Harned, Scatchard, Pitzer and Lim-HOLL treatments. All these methods are adequate for the analysis of the experimental data. The results have been compared with those of Lanier for the system: NaCl + NaClO4 + H2O. The Gibbs excess energy of miring was obtained and qualitatively interpreted in terms of ionic interactions.
