Donnan Potential-Regulated Interaction Between Porous Particles

2 TWO PARALLEL SEMI-INFINITE ION-PENETRABLE MEMBRANES (POROUS PLATES) [Pg.298]

Consider two parallel semi-infinite membranes 1 and 2 carrying constant densities Pfixi and Pfix2 of fixed charges separation fi between their surfaces in an electrolyte solution containing N ionic species with valence Zi and bulk concentration (number [Pg.298]

FIGURE 13.1 Various types of positively charged ion-penetrable porous particles with fixed charges (large circles with plus sign). Electrolyte ions (small circles with plus or minus signs) can penetrate the particle interior. [Pg.299]

We also assume that the relative permittivity in membranes 1 and 2 tale the same value as that of the electrolyte solution. Suppose that membrane 1 is placed in the region —00 x 0 and membrane 2 is placed in the region x h (Fig. 13.2). The linearized Poisson-Boltzmann equations in the respective regions are [Pg.299]
