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.

Adsorption equilibrium and kinetics of Caffeine and Nicotine from aqueous solution on activated carbon were determined experimentally in a batch system. Then, the equilibrium data were expressed by the Freundlich type and the equilibrium constants were obtained. Diffusion coefficient were determined by comparing experimental decay curve with theoretical ones. Surface diffusion was consided to be dominant and the value of diffusion coefficient were depent of the amount adsorbed and the equilibrium concentration. Domestic activated carbon has nearly same amount of adsorption as imported activated carbon made by CALGON carbon Corp.

The purpose of this paper was to separate the copper and nickel ions from waste water using supported liquid membrane The effect of a given amount of carrier and ammonia concentration of up-stream was described. We used the LIX65N as carriers. The results were as follows 1. The distribution ratio of copper ions at equilibrium was shown linear increment according o the mole ratio of carrier concentration versus the concentration of metal ions increased to 2.0. The maximum distribution ratio of copper ions exceeded that of nickel by approximately 4-fold when the liquid membrane was saturated by carrier 2. The important parameters governing flux were carrier and ammonia concentration. We compared these two parameters, and then the latter influenced more than the former to get higher flux. The copper ions reacted with ammonia in the up-stream, it formed a complexes of Cu(NH₃)₄^(2+), and then diffused to interface of liquid membrane. 3. The flux of metal ions were increased with enlarging the distribution ratio of ordinary extraction. The principle of coupled transport was carried out by the difference of concentration of hydrogen ions. 4. We can be selectively separated in the mixing soultion of copper and nickel ions using LIX65N as carrier.
