Abstract:
Mathematical model of the volume flux through neutral polymeric membrane with concentration boundary layers on both sides of this membrane is presented. This model was based on the Kedem-Katchalsky equations for electrolyte solutions and describes the volume flux generated by osmotic and hydrostatic forces for dissociating substance non-homogeneous solutions. Nonlinear equation for volume flux was used for numerical calculations in linear regime of hydrodynamic stability. The validity of this model for binary solutions was confirmed by using a cell with a vertically mounted membrane. In the experimental set-up aqueous solution of KCl was placed on one side of the membrane. Whereas the ammonia in aqueous solution of KCl was placed at the other site of the membrane The good correlation between the experimental data o J(vm) and the results of calculation based on the model equations of J(vm) was observed.

Pore Transport and Ion-Pair Transport
Pore transport, also known as convective transport, is a process where small molecules like urea, water, and sugars rapidly cross cell membranes as though there were channels or pores in the membrane. Although direct microscopic evidence is limited but the concept of pores or channels is widely accepted based on physiological evidence. Despite the lack of direct microscopic...
Theories of Dissolution: Diffusion Layer Model
This process starts with a thin layer, saturated with the drug, forming at the interface between the solid and liquid. The solute then diffuses from this layer into the main solution. The Noyes-Whitney equation suggests that the rate of dissolution relies on the diffusion...
