Structural Parameters of Membranes from Porous Glass in Aqueous Solutions of Electrolytes, Containing Singly-Charged (Na+, K+) and Triple-Charged (Fe3+) Cations

The structural parameters of micro- and macroporous glass-like membranes in the solutions containing sodium, potassium, and iron counterions were investigated. The dependences of the volumetric porosity of the membranes, structural resistance coefficients, filtration coefficients, specific surface, average pore radius on the conditions of obtaining porous glass, the composition of the electrolyte, and the contact time of the porous glass with the solution are analyzed.
