Abstract

1421531 Selective sorption UNITED KING- DOM ATOMIC ENERGY AUTHORITY 29 Nov 1972 [15 Dec 1971] 58374/71 Heading B1H [Also in Division C1] In making discrete particles for the selective retention of macromolecules, finely-divided solid particles of a sorptive inorganic material are mixed with a fugitive additive and a solvent therefor, the inorganic material being insoluble in the solvent, the mixture is formed into discrete green particles containing the fugitive additive in solid form, and the green particles are then heated to remove the fugitive additive and cause sintering of the inorganic material to provide discrete particles having an interconnected pore structure capable of penetration by macromolecules. A sorptive inorganic material is defined as one that is capable of retaining macromolecules by adsorption or absorption or which can be treated to make it so capable, e.g. titanium dioxide, alumina, calcium phosphate, larium sulphate, calcium sulphate, a zirconium oxide, or natural earths such as celite. Specified fugitive additives are ammonium carbonate, haemoglobin, polyvinyl alcohol, dextran, urea, lorine serum albumin and ovalbumin. The green particles, e.g. spheroids, are suitably formed by spray-drying or by vibration (see Specification 1033143). The final sintered aggragate particles may be 50-600Á in size, having interconnected pores of 1000-10000Š. The products are used for selective sorption of macromolecules from fluids, and may be tailored to sorb particular macromolecules by selecting appropriate preparative conditions and fugitive additive. In one example, TiO 2 (<10Á) is slurried in a mixture of aqueous ammonium carbonate solution and glycerol, as a binder. The product is dried and the resulting particles are sieved and then spheroidized to form green spheres (50-500Á), which yield porous spheres on heating to 900‹C for 2 hours. In further examples, porous particles of Ca 3 (PO 4 ) 2 , BaSO 4 , Al 2 O 3 and celite are produced, and the use of TiO 2 particles in protein separation is exemplified. Suitable combinations of inorganic sorptive material, fugitive additive and preparative coaditions for partioular purposes are suggested.
