    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.

    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.
