详细

Modification of membranes by pyrocarbon was carried out by carbonization of polyisocyanate, celluloacetate and Na-salt of carboxylmethyl cellulose at 750°C. The water was purified of dyes by the pressure-driven method under pressure from 0.1 to 1.1 MPa. The retention coefficient and specific capacity of modified membranes for direct scarlet vary respectively from 37 to 99.99% and from 1.8 to 36 dm3/(m2 • h). For membranes with carbonized cellulose ethers the retention rate for brilliant green vary from 19 to 78.5% and the specific capacity depending on pressure and filtration time varies from 8.1 dm3/(m2 • h) to ~ 1 m3/(m2 • h).
