Conductivities of CuSO4 and CdSO4 in sucrose/trehalose-water systems at 298.15 K / Kelei Zhuo in Industrial & engineering chemistry research, Vol. 48 N° 13 (Juillet 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 13 (Juillet 2009) . - pp. 6432–6435 Titre : Conductivities of CuSO4 and CdSO4 in sucrose/trehalose-water systems at 298.15 K Type de document : texte imprimé Auteurs : Kelei Zhuo, Auteur ; Yujuan Chen, Auteur ; Wenhao Wang, Auteur Année de publication : 2009 Article en page(s) : pp. 6432–6435 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : CuSO4  CdSO4  Aqueous  disaccharide  Sucrose/trehalose-water  systems Résumé : The conductivities of CuSO4 and CdSO4 in aqueous disaccharide (sucrose and trehalose) solutions were measured together with the densities, viscosities, and relative dielectric constants of the aqueous disaccharide solutions at 298.15 K. The limiting molar conductivities (Λ0) and association constants (KA) were derived from the Lee−Wheaton conductivity equation. From the obtained conductivity data, the values of the Walden product (Λ0η0) were also calculated. The ion−ion and ion−solvent interactions are discussed.

Individual ionic activity coefficients of sodium halides in glucose − water solutions at 298.15 K / Weiyan Dong in Industrial & engineering chemistry research, Vol. 49 N° 19 (Octobre 2010) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 49 N° 19 (Octobre 2010) . - pp. 9430-9435 Titre : Individual ionic activity coefficients of sodium halides in glucose − water solutions at 298.15 K Type de document : texte imprimé Auteurs : Weiyan Dong, Auteur ; Yang Zhao, Auteur ; Kelei Zhuo, Auteur Année de publication : 2010 Article en page(s) : pp. 9430-9435 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Thermodynamic  properties  Activity  coefficient  Ionic  activity Résumé : The individual ionic activity coefficients of sodium halides (NaX) in the NaX−glucose−water solutions were experimentally determined at 298.15 K by using ion selective electrodes. The individual ionic activity coefficients evaluated by the use of the extended Debye—Hückel equation are in agreement with those by the Pitzer equation. In addition, dependences of the individual ionic activity coefficients upon molalities, properties of cations and anions are discussed.
