Estimation of activity coefficients in concentrated sulfite‐sulfate solutions

“…Values for ion pairs of interest in flue-gas desulfurization chemistry appear in Table 1 (ion-pair parameters) and Table 2 (interaction Coefficients). Using these empirical parameters, as shown at length by Pitzer Mayorga, 1973,1974;Pitzer and Kim, 1974) and others (Khoo et al, 1977a, 197713, Culberson et al, 1978; Holmes et al, 1979;Harvie and Weare, 1980), Eqs 1-7 reproduce experimental data for pure electrolytes and for mixtures usually to within better than 2% and in all cases to *0-20%.…”

Activity coefficients in mixed-electrolyte solutions

“…On the other hand, a curve-fitting procedure will provide the flexibility of allowing OMN, OhN and t//MNx to be determined singly or in combinations, as shown by Khoo et aZ. 32 for HCl-CaCl, mixtures, for which the derived Pitzer equations 91n 10…”

Application of the GV-MSA model to the electrolyte solutions containing mixed salts and mixed solvents

“…(35) and (36) to the experimental data [31] of the dielectric constants and densities of the solvents in the mixed-solvent of water and alcohol electrolyte solutions, respectively, at 25 • C. These equations were directly used in the models studied in this work to predict the MIAC of electrolytes in the mixed-solvent electrolyte solutions. Table 3 gives the values for the adjustable parameters for the single aqueous electrolyte solutions, which can be used in the GV-MSA1, GV-MSA2 and the Pitzer models, respectively.…”
