Silver Solubility in Supercritical Fluids in a Wide Range of NaCl Concentration (0.6-50 wt %)-Experimental and Thermodynamic Description
The solubility of Ag-cr has been measured in a 0.1m (mol center dot(kg H2O)(-1)) solution of HCl at a fixed hydrogen content (similar to 0.5m) as a function of NaCl concentration from 0.1 to 18m at temperatures ranging from 425 to 475 degrees C and pressures of 500 and 1000 bar. It is found that AgCl2- is a dominant species in the whole range of NaCl concentrations (up to 50 wt %). By the treatment of the experimental data, the applicability of the Debye-Huckel and the Setchenov-type equations was tested. The solubility data over the entire NaCl concentration range is accurately (within the experimental uncertainty of 0.1 log m(Ag)) described by the reaction Ag-cr + HClaq + Cl- = AgCl2- + 0.5 H-2aq K-s and simple equations for activity coefficients log gamma(i) = (Azi(2)root I)/(1 + (a) over circleB root I) + Gamma(gamma) + b(gamma) center dot I (for charged species) log gamma(n) = Gamma(gamma) + b(n) center dot I (for neutral species) where (a) over circle = 4.5 angstrom and b(gamma) = 0 for all charged species, b(n) = 0 for all neutral species, Gamma(gamma) = -log(1 + 0.018m*), m* is the sum of the concentrations of all solute species. The values of the Ag solubility constant and log K-s are determined as -0.33 +/- 0.03 (425 degrees C/1000 bar), -0.19 +/- 0.02 (450 degrees C/500 bar), and -0.10 +/- 0.04 (475 degrees C/1000 bar). For the most concentrated solutions (5-18m NaCl), the experimental data description can be slightly improved by accepting the Setchenov parameter b(n) = 0.05, but the accurate determination of the b(n) value requires additional experimental studies. It should be noted that this approach was developed for a simple system with a 1:1 background electrolyte, which is free of multi-charged species.
