From the experiments on the adsorption of binary mixtures of benzoic acid-phenol in the fixed bed column packed with activated carbon, the following results are obtained. 1. For the equilibrium adsorption of unicomponent and binary system are fairly well consistent with freundlich's equation. 2. The breakthrough time and selective separation are linearly increased with the lengh of adsorption column. And the slope of benzoic acid which has large equilibrium adsorption is larger than that of pherol. 3. The substitunt coefficients increase with the concentration ratio. 4. The increase in the flow rate does not bring the equivalent increase in the breakthrough time.

Uptake curves were obtained for p-nitrophenol/XAD-2000 resin system using a shallow-bed method for various concentration ranges at 298.2K. Distilled water was employed as solvent. The values of effective intraparticle diffusivity were detrermined by comparing experimental and theoretical uptake curves. The values obtained for solvent i. e, distilled water system was not dependent on the amount adsorbed in the higher concentration range. Those results shows that, except in the region where there is a low adsorbed amount, and adsorber packed with macrorecticular resin particles can be designed using a traditional pore diffusion model.
