Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 6 (Mars 2009) . - pp. 2781–2785 Titre : High-temperature conductivity measurements of concentrated NaCl-H2SO4-H2O solutions up to 250 °C Type de document : texte imprimé Auteurs : Ming Huang, Auteur ; Vladimiros G. Papangelakis, Auteur Année de publication : 2009 Article en page(s) : pp. 2781–2785 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Electrodeless  conductivity  cell  NaCl-H2SO4-H2O  solutions  Ionic  conductivity Résumé : An electrodeless conductivity cell was employed to investigate the electrical conductivity of concentrated NaCl−H2SO4−H2O solutions particularly at high temperatures. All solutions were measured from 25 to 250 °C at the equilibrium vapor pressures. The maximum measured concentrations of NaCl and H2SO4 were 0.40 and 0.45 m, respectively. At 250 °C and a fixed concentration of H2SO4, the conductivity of NaCl−H2SO4−H2O solutions increases with the increasing concentration of NaCl. Similarly, at 250 °C and a fixed concentration of NaCl, the conductivity of NaCl−H2SO4−H2O solutions increases with the increasing concentration of H2SO4. It was found that the ionic equivalent conductivity of H3O+ is a function of ionic strength at 250 °C and is independent of the solution speciation.
