The structural and electrokinetic characteristics of ultra-and nanoporous glasses produced from basic sodium borosilicate glass have been investigated in tetraethylammonium chloride solutions. Colloido-chemical characteristics of the membranes have been compared with those determined in sodium and potassium chloride solutions. It has been found that the regularities of variations in counterion transference numbers and efficiency coefficients are related to a decrease in tetraethylammonium cation mobility in the membranes.
