    摘要： A method for the separation of the isotopes of carbon comprising contacting an aqueous solution containing an acid-dissociated type chemical species of a carbon-containing acid and a non-dissociated type chemical species of said acid with an anion exchange resin as a solid phase, thereby to allow an isotope exchange reaction with respect to carbon to proceed between said acid-dissociated type chemical species and said non-dissociated type chemical species and, concurrently, to adsorb said acid-dissociated type chemical species on said anion exchange resin, and separate C.sup.12 and C.sup.13 respectively into a solution phase and the solid phase or the solid phase and a solution phase, whereby C.sup.13 is concentrated. This method can be practised at an extremely favorable efficiency and inexpensive cost, as compared with the prior art method for the separation utilizing a distillation method or a chemical exchange method between gas--liquid phases, gas--solution phases, solution--solution phases and the like.

    摘要： An isotope separation apparatus comprises a plurality of independent developing units, each comprising 2 to 20 adsorbent-packed columns forming a continuous developing circuit or passageway, and the developing units are connected to at least one common main pipe for supplying an isotope mixture solution, a regenerating agent solution, or an eluent solution. Also, in a further embodiment the developing units are connected to common liquid-discharge main pipes.The separation or concentration of isotopes such as uranium isotopes, nitrogen isotopes, boron isotopes, etc., is performed by continuously developing the isotope mixture solution passed through the individual adsorbent-packed columns successively in each developing units.

    摘要： A novel protein adsorbent consisting essentially of a porous copolymer obtained by copolymerizing a monomer mixture comprising at least one cyano group-containing monomer and at least one cross-linkable monomer, said copolymer having an average pore diameter (d) of from 40 A to 9,000 A and a total pore volume of from 0.05.sqroot.X ml to 1.5.sqroot.X ml per gram of the copolymer in a dry state, in which X designates the weight proportion of said cross-linkable monomer expressed in terms of the percent by weight based on the total monomers. The present porous copolymer adsorbent has a remarkably high protein adsorbing capacity. The adorbent can advantageously be used for various purposes such as purification and separation of proteins, and removal of proteins. Copolymer-protein composites obtained by adsorption of proteins on the present porous copolymer also are industrially useful and have a wide variety of applications.
