Abstract:
1. A method of mass-exchange sorption at processing an aqueous solution of inorganic substances for separation its components, comprising: passing an aqueous solution that is being processed through a layer of granulated sorption material; wherein space available for the aqueous solution that is being processed, between granules in the layer of granulated sorption material, is reduced, wherein as said layer, is used a layer of hydrophilic granulated sorption material selected from a strong base anion exchange resin or a strong acid cation exchange resin, this layer being under pressure on the order of 0.1 bar for prevention of its fluidization; wherein for reduction of the space available for the aqueous solution that is being processed, between the granules in the layer of hydrophilic granulated sorption material, this layer is previously substantially filled with an organic liquid or the mixture of organic liquids, which are not miscible with water and with the aqueous solution that is being processed and does not chemically react with components of the aqueous solution that is being processed and with said hydrophilic granulated sorption material; and wherein the solution that is being processed introduces along a phase boundary between the said organic liquid or the mixture of organic liquids and a surface of the granules in said layer of the hydrophilic granulated sorption material, coating thereby each granule of said sorption material with a finest flowing film that flows via the points of contact of the coated granules.
