In recent years, ionic liquids have been used in pharmaceutical processes. Therefore, having a deep insight into the ion association behavior of ionic liquids in the presence of a drug is of particular importance. So, in this work, the molar conductivities of the ionic liquids, 1-alkyl-3-methylimidazolium bromide, [CnMIm]Br (n = 4, 6 and 8) in various concentrations of aspirin (ASA) ...

The development of direct methanol fuel cells required the attention to the electrolyte. A good electrolyte should not only be ionic conductive but also be crossover resistant. Ionic liquids could be a promising electrolyte for fuel cells. Monitoring methanol was critical in several locations in a direct methanol fuel cell. Conductivity could be used to monitor the methanol content in ionic liq...

This work explores the possibility of increasing the ionicity of ionic liquids via the solubilization of inorganic salts in their midst. The resulting purely ionic media-distinct ionic liquid plus inorganic salt mixtures-are liquid in an extensive concentration range and can be aptly denominated High Ionicity Ionic Liquids (HIILs).

OBJECTIVES In this study, we investigated the influence of ionic strength and natural organic matter (NOM) on aggregation and soil adsorption of citrate-coated silver nanoparticles (AgNPs). METHODS Time-resolved dynamic light scattering measurements and batch adsorption experiments were used to study their aggregation and soil adsorption behaviors, respectively. RESULTS The aggregation rate...

in this study, the blast furnace slag was used as absorbing bed and then, its ionic adsorption was studied. for this reason, various experimental parameters such as ph, contact time and the primary ion concentration were investigated. the remaining concentrations of ions such as; mn2+ and fe2+ in water were measured by atomic adsorption spectroscopy. the chemical and phase composition of slag, ...

Bulk ionic conductivity, Ionic Thermal Current (I.T.C.), and Thermally Stimulated Polarization Current (T.S.P.C.) studies are reported for the system Bal-,LaXF2+, (0.12 x loe2 < x < 0.45). The obtained results are illustrative for the compositional dependence of the ionic conductivity of anion-excess solid solutions. For small solute content simple associates as well as free mobile fluoride int...
