Styrene-divinylbenzene eopolymer beads of 40% crosslinking were first sulfonated with concentrated sulphuric acid and then pyrolyzed under nitrogen atmosphere in a cracking furnace. The properties pf the carbonaceous absorbent were correlated with its structures such as the surface area
the distribution of pore diameters
density
strength
etc. The surface area exceeds 800M2/g
and the porosity for the adsorption of ereatinine and uric acid is over 98%. The optimum pore diameters of the adsorbent for the adsorption ofuric acid are 6---40A. Larger diameters (160--170A). Facili-tate the diffusion of creatinine and uric acid into the pores and be adsorbed therein.
