Nanofiltration of air from organic pollutants by composite membranes
Abstract
Nanofiltration membranes were used to separate a gas-air mixture containing organic compounds. The membrane was obtained on a substrate of filter paper by watering with a three-component polymer solution. The surface layers were applied to the substrate by sequentially alternating the drying steps of the membrane. The retention capacity of the membranes was investigated by separating model gasoline-air mixtures. The average retention capacity of the membranes obtained was close to 90 %, and more than 90 % for aromatic compounds.
