Quantitative description of ion transport in Donnan ion exchange membrane systems
- Hoeschst Fibers, Spartanburg, SC
Presented are simplified mass transfer techniques describing the transfer of ions in continuous ion selective membrane systems in which the resistance to ion transport through the membrane is small in relation to the resistance to ion transport in the solution phase. Methods are developed through the application of the transfer unit concept to the Donnan equilibrium. This equilibrium describes the equilibrium ion concentration on either side of an ion selective membrane. Data from one cation selection system is presented as evidence of the validity of these methods. Further techniques are shown that will allow the determination of ion transport given only equipment parameters and solution diffusivities. Supporting data are shown.
