Abstract
The temperature dependence of the selectivity and filtration flow rate of reverse-osmosis polyamide membranes modified by various liquid cry stals with crown-ether (dibenzo-18-crown-6) microadditives is studied. The effects of two distinct modification methods on the membrane perf ormance were evaluated and discussed. The measurements of selectivitie s and filtration flow rates were performed on electrolytic solutions o f NaCl and KCl.
