Behavior of the aqueous sodium chloride solutions from molecular simulations and theories
نویسندگان
چکیده
Molecular simulations and theories are important tools for studying electrolyte solutions. In this work, molecular dynamics with one of the most widely used force field combination water alkali halide monovalent ion parameters were first conducted aqueous sodium chloride solutions to predict density, self-diffusion coefficients molar conductivity. Then radial distribution functions analyzed obtain shell solvation radii coordination numbers ions, which found practically unchanged against concentration. Together parameters, they further applied into various Gibbs energy solvation, static relative permittivity, mean ionic activity It is remarkable see that conductivity can be predicted deviations 1.1 % 1.4 %, respectively, up 6 mol/kg H2O.

15 صفحه اولApplication of capacitive deionization technology to the removal of sodium chloride from aqueous solutions
Capacitive deionization has been developed as a promising desalination alternative for removing ions from aqueous solutions. In this study, the evaluation of capacitive performance was carried out by galvanostatic charge/discharge and cyclic voltammetry experiments. The good capacitive and electrosorption behaviors suggest carbon aerogel not only treated as an electrical double layer capacitor,...

Nor was the normal rate of loss of 2,3-diphosphoglycerate, ATP, or glutathione from the red cells affected by the presence of chloramphenicol over the same period. Consequently, this bacteriostatic agent can be added to blood samples taken under nonsterile conditions, such as from the heel of an infant, in order to preserve them from the effects of micro...
