2.2.4 Calculation of
activity coefficient for component two (solute)
As a consequence, the sorption parameters and the solvent
activity coefficients and the Flory Huggins parameters were calculated only in the temperature range from 60 to 80[degrees]C and for polar-type and dispersion-type solvents in whose retention diagrams this decreasing linear zone can be clearly observed.
Activity coefficients of all species are assumed to be independent of pressure.
The
activity coefficients and other thermodynamic properties of hydrochloric acid are dependent not upon the value of E[degrees] but on the difference E-E[degrees].

where [(g.sup.GT.sub.K] and [N.sup.GT.sub.Ca] are the respective adsorbed
activity coefficients of the K and Ca ions; [N.sub.K] and [N.sub.Ca] are the respective equivalent fractions of [K.sup.+] and [Ca.sup.2+] on the exchanger; [[gamma].sub.K] and [[gamma].sub.Ca] are the
activity coefficients of [K.sup.+] and [Ca.sup.2+] in the equilibrium solution; and [M.sub.K] and [M.sub.Ca] are the [K.sup.+] and [Ca.sup.2+] molarities in the equilibrium solution.
The apparent suppression of Na/K data obtained with ion-selective electrodes is due to junction potential and
activity coefficient effect, not to bicarbonate binding [Letter], and Coleman RL, Young CC [Reply].
By obtaining the weight fraction
activity coefficient, 1, the partial molar free energy, DG1 , and the average partial molar enthalpy, DH1 values can be calculated from following relations, respectively at infinite dilution [31-33].
Deviation from ideality is accommodated by modifying the
activity coefficient. Mass balance equations are solved under the constraint of Raoult's law to determine the extent to which MF evaporates.
Impurity elements effect in different way
activity coefficient of phosphorus and, therefore, activity of phosphorus in ferronickel.
General results are based on ([partial derivative][g.sup.E]/[[partial derivative][x.sub.1]).sub.az] = R[T.sub.az] In[[p.sub.2.sup.*]([T.sub.az])/[p.sub.1.sup.*]([T.sub.az])], and [P.sub.az] = [([gamma].sub.1][p.sub.1.sup.*]).sub.az] = [([gamma].sub.2][p.sub.2.sup.*]).sub.az], where R is the gas constant, [p.sub.*] is saturation vapour pressure, and [gamma] is liquid-phase
activity coefficient. Specific results are given for the Redlich-Kister, van Laar, Wilson, and NRTL equations.
where m is the equilibrium concentrations (mol/L), [gamma]N[H.sub.4] is the single ion
activity coefficient for N[H.sub.4.sup.+], and [gamma]Ca is the single ion
activity coefficient for [Ca.sup.2+].
