Ultrafiltration membranes were obtained by means of modification of microfiltration ceramic membranes with pyrocarbon from polyisocyanate and sodium carboxymethyl cellulose. For Ca 2+ the retention factor and the specific productivity of the modified membranes depend on their composition and filtrat...
