COMPOSITE ION-EXCHANGE MEMBRANE Russian patent published in 2014 - IPC B01D71/02 B01D71/06 B82B3/00

Abstract RU 2527236 C1

FIELD: chemistry.

SUBSTANCE: claimed is composite ion-exchange membrane, characterised by higher mobility of nitrate-anions and higher constant of ion exchange with respect to nitrate-anion. Membrane contains ion-exchange polymer matrix, which is volume- or gradient- modified with cerium oxide nanoparticles.

EFFECT: efficient application of obtained membrane in processes of purification of various solutions, including liquid food products, from nitrate-anions.
