Abstract: This invention relates to a method for improving the performance of liquidembrane separations by coating a liquid membrane onto solid ion-exchange resin beads in a fixed bed. Ion-exchange beads fabricated from an ion-exchange resin are swelled with water and are coated with a liquid membrane material that forms a film over the beads. The beads constitute a fixed bed ion-exchange column. Fluid being treated that contains the desired ion to be trapped by the ion-exchange particle is passed through the column. A carrier molecule, contained in the liquid membrane ion-exchange material, is selected for the desired ion in the fluid. The carrier molecule forms a complex with the desired ion, transporting it through the membrane and thus separating it from the other ions. The solution is fed continuously until breakthrough occurs at which time the ion is recovered, and the bed is regenerated.

Abstract: A process is described for removing low density and very low density lipoproteins from blood plasma or serum and recovering the plasma or serum in a physiologically acceptable form. The method involves in a preferred embodiment passing plasma or serum through a cationic ion exchanger equilibrated with a physiologically acceptable saline solution. The ion exchanger is a water insoluble hydrophilic, water swellable cross-linked regenerated or microgranular cellulose matrix substituted with hydroxy C.sub.2 -C.sub.4 alkyl group. The ion exchanger capacity is provided by sulphate groups substituted with from 2 to 6 meq/g. The take up of low density lipoproteins is enhanced by recycling the plasma through the column.

Abstract: Ammonia or an amine such as morpholine is recovered from a resin bed comprising an alkali metal, e.g., sodium, and ammonium or amine salts of a strong acid cation exchange resin by contacting the cation resin with an aqueous solution of an alkaline earth metal hydroxide, e.g., calcium hydroxide, thereby exchanging the alkali metal and ammonium or amine cations with alkaline earth metal cations. The aqueous liquid containing the alkali metal and ammonia or amine is subsequently passed through a cation exchange resin which removes the alkali metal from the liquid. The recovery of ammonia or the amine by such method is particularly useful in condensate purification system associated with a power production facility wherein the recovered ammonia or amine can be employed to reduce corrosion in the power production facility and the strong acid resin, upon regeneration, can be used to remove alkali metal ions, particularly sodium, from the facility.

Abstract: An improvement in processes for recovering aluminum from alunite ore which processes include roasting the ore to remove water of hydration, removing sulfur and potassium compounds from the roasted ore by a procedure including a final leaching step resulting in a residue and a solution containing potassium sulfate, effecting partial recovery of potassium sulfate from the solution by crystallization with some potassium sulfate being bled off from the mother liquor, converting aluminum values in the residue to alkali metal aluminates by digesting the residue with alkali metal hydroxide including a substantial amount of sodium hydroxide, removing silicon from the alkali metal aluminates leaving a waste desilication product, recovering aluminum values from the desilicated aluminates by precipitation, circulating the mother liquor from the precipitation step to digestion as contaminated sodium hydroxide is bled off, the improvement which comprises enhancing the economics of the overall process by introducing therein an ion exchange procedure in which potassium hydroxide for the first leaching step is produced through ion exchange by use of potassium sulfate and sodium hydroxide, a further improvement being the use of the desilication product as the ion exchange agent.
