Electro-osmotic pumping of sodium chloride solutions
Electro-osmotic pumping (EOP) theory and its characteristics (transport numbers, brine concentration, current density, current efficiency, electro-osmotic coefficients, etc.) of Selemion AMV and CMV ion-exchange membranes were studied. The brine concentration increased with increase in current density and feed water concentration. Current efficiency was nearly constant in a wide range of curren...
متن کاملElectro-osmotic flow of semidilute polyelectrolyte solutions.
We investigate electro-osmosis in aqueous solutions of polyelectrolytes using mean-field equations. A solution of positively charged polyelectrolytes is confined between two negatively charged planar surfaces, and an electric field is applied parallel to the surfaces. When electrostatic attraction between the polymer and the surface is strong, the polymers adhere to the surface, forming a highl...
متن کاملOsmotic volumes of distribution; idiogenic changes in osmotic pressure associated with administration of hypertonic solutions.
A RECENT paper from this laboratory (I) showed that the osmotic volume of distribution of sodium numerically approximates total body water when either sodium chloride or sodium sulfate is loaded in anesthetized, nephrectomized dogs and cats. The question of why these two sodium distributions appear to be identical was deferred. In extending osmometric analysis to this and related matters, we ex...
متن کاملSalt Effect on Osmotic Pressure of Polyelectrolyte Solutions: Simulation Study
We present results of the hybrid Monte Carlo/molecular dynamics simulations of the osmotic pressure of salt solutions of polyelectrolytes. In our simulations, we used a coarse-grained representation of polyelectrolyte chains, counterions and salt ions. During simulation runs, we alternate Monte Carlo and molecular dynamics simulation steps. Monte Carlo steps were used to perform small ion excha...
متن کاملOsmotic and Structural Properties of Biopolymer Solutions and Gels
Introduction Interactions between cations (e.,g., Ca, Na, K) and charged biopolymers are implicated in a wide-range of physiological processes including nerve excitation, muscle contraction, ion channel dynamics, etc. Study of the thermodynamic and structural aspects of ion/polymer interactions has the potential to contribute to a more comprehensive understanding of ion mediated structural orga...
