The Gibbs-Donnan effect - Deranged Physiology
2015年6月27日 · The Gibbs-Donnan effect is the phenomenon of predictable and unequal distribution of permeant charged ions on either side of a semipermeable membrane, in the presence of impermeant charged ions.
Donnan Effect - an overview | ScienceDirect Topics
The separation through NF membranes is the integrated outcome of Donnan, transport, dielectric, and steric effects. The Donnan effect refers to the equilibrium and interaction between a soluble charged molecule and charge existing on membrane (Donnan, 1995).
Donnan Effect - SpringerLink
2015年12月23日 · The Donnan effect (which is named after the British chemist Frederick George Donnan (Donnan 1911, 1995) is related to the presence of impermeant ions (i.e., ions that are unable to pass through a semipermeable membrane or boundary) upon one side of a boundary on the distribution of permeant ions across the boundary. At equilibrium, the co-ions ...
The Donnan Membrane Principle: Opportunities for Sustainable …
2010年1月21日 · Scientifically, the Donnan membrane effect, or Donnan potential, is distinctly different from the effect of surface charges often present at the solid/liquid surface. Nearly 90 years ago, a detailed thermodynamic explanation of the underlying principle was introduced by Frederick G. Donnan (9).
Gibbs-Donnan Effect - an overview | ScienceDirect Topics
The differences in pH and electrolyte concentrations are characteristics of the Gibbs-Donnan effect whereby the high concentration of anionic proteins in plasma draws sodium and potassium from the interstitium, and chloride follows the cations in an attempt to preserve electroneutrality.
Donnan Exclusion Effect - an overview | ScienceDirect Topics
The Donnan exclusion effect, also known as the Gibbs-Donnan effect, is used to describe the distribution of charged ions near a permeable membrane for the organism.
Calculation of the Gibbs–Donnan factors for multi-ion solutions …
Here, we present a method of calculating the G–D factors for ideal electroneutral multi-ion solutions with different total charge of non-permeating species on each side of a permselective membrane separating two compartments.
Gibbs-Donnan effect - chemeurope.com
The Gibbs-Donnan effect (also known as the Donnan effect, Donnan law, Donnan equilibrium, or Gibbs-Donnan equilibrium) is a name for the behavior of charged particles near a semi-permeable membrane to sometimes fail to distribute evenly across the two sides of the membrane.
Donnan Effect Patrick Fievet Institut UTINAM, University of Franche-Comté, Besanc¸on, France The Donnan effect (which is named after the British chemist Frederick George Donnan (Donnan 1911, 1995) is related to the presence of impermeant ions (i.e., ions that are unable to pass through a semipermeable membrane or
Gibbs-Donnan Equilibrium - Resting Membrane Potential
2014年2月15日 · At Gibbs-Donnan equilibrium, this unequal permeability leads to a greater total solute (ions + proteins) concentration in the cell than in the extracellular environment. The greater osmolality in the cell, thus, draws water into the cell by osmosis, leading to cell swelling.
