Effect of quaternary ammonium salts on the separation efficiency of nanofiltration membranes

In case of salicylate, the decrease was significant, onto values in the range of 12%-22% for salicylate, and to the range of 86%-91%, regarding bromide. This observed phenomena could cause a new possibility of increasing the separation efficiency of monovalent ions from a multicomponent system with the aid of nanofiltrating membranes.
