The electrical conductances of dilute solutions of the ionic liquids 1-ethyl-3-methylimidazolium tetrafluoroborate [emim]BF 4 and 1-butyl-3-methylimidazolium tetrafluoroborate [bmim]BF 4 in N,N-dimethylformamide have been measured over the temperature range from (283.15 to 318.15) K. The ionic association constant, K A , limiting molar conductivities, Λ o , and distance parameters, R, were obtained using the Fuoss−Justice equation for the investigated systems. Slight ion association effect was found for the ionic liquids in DMF at all experimental temperatures. From the temperature dependence of the limiting molar conductivities the Eyring's activation enthalpy of charge transport was estimated. The thermodynamic functions such as Gibbs free energy, entropy, and enthalpy for the process of ion pair formation were calculated from the temperature dependence of the ion association constants.

“…It is noteworthy that this result is in good agreement with the experimental studies by Szejgis et al that by increasing the organic solvent content, the size of the solvation shell increased and the mobility of the cation was reduced. 71 Time evolution of the vdW and electrostatic interactions between the gel contents in the MG1, MG2, and MG3 systems are investigated in detail (Fig. S3 and S4 †).…”

Most of what is known about the environmental fate and transport of contaminants comes from studies of dilute, aqueous solutions. Theoretical and practical aspects of hydrophobic organic contaminants in aqueous mixtures of organic solvents are well developed, but relatively little attention has been paid to those situations where inorganic contaminants such as metals, water, and organic solvents occur simultaneously. The authors discuss changes in solution properties accompanying the addition of organic solvents. They review more than 500 references to available data on ion solvation, solubility, activity, acidity, pairing, and pH in electrolyte and electrolyte-free solvent mixtures and tabulate selected experimental values. Whenever available, equations developed to estimate these properties are given and their applications and limitations described. The implications of the progress in mixed-solvents solution chemistry on contaminant behavior and transport are described. Major limitations to the study of inorganic contamination in mixed solvents include the absence of complete and comprehensive data (e.g., type of ionic species, activity coefficients, solubility constants) that characterize solute and solvent properties in these mixtures and the indefinite number of possible solute and solvent combinations. The generation of models predicting such data from easily measured benchmark solute and solvent properties is a major challenge. The availability of such database and models may open the field for environmental engineers and soil scientists to study the basic chemical processes and mechanisms of metal contamination in complex multicomponent systems.
