摘要：
A novel chromatomembrane method for the continuous separation of substances was developed. Mass exchange in liquid-liquid and liquid-gas systems proceeds according to chromatographic principles. Capillary effects in porous hydrophobic membranes with two preferential pore types are utilized to realize independent transport of phases in arbitrary directions. The macropores form channels for the polar liquid phase. The non-polar liquid or gas phase passes through the micropores, which are inaccessible to the polar phase because of capillary pressure. The possibilities of the method are demonstrated by schemes of continuous separation with preset extraction coefficients, schemes of application of the method in flow-injection analysis and results obtained in chromatomembrane blood oxygenation.
