From: The development of pressure across membranes in Donnan systems
Scheme of a Donnan system.
The value of x is set to 0 at the interface of a pore within the membrane with the solution on side 2. The charged polymer is excluded from the pore due to its size. The length of the pore, i.e., the thickness of the membrane, is >103 Å. The membrane is permeable to solutes and water only due to the presence of its pores.
