초록정보

Adsorption isotherms of solute in organic solution were measured in a concentration range of 1 - 40 mole / ㎥ on silica gel at 30℃. The selected isotherms for each component were successfully fitting the experimental data over the concentration range. And for the binary system, the competitive adsorption was studied. In a batch system, the external mass transfer coefficient was determined using correlation equation. To select the model describing the system well, film pore diffusion model and film solid diffusion model using nonlinear isotherm were tested for the experimentally estimated time concentration curve. The diffusion model using the approximated linear isotherm developed in this study was described to the experimental results, well. The effective solid diffusivities determined in single component system were dependent on the initial concentration of the adsorbates in the liquid. For the binary adsorption, the effective diffusivities were determined from the nonlinear isotherm. The effective solid diffusivities of m-Cresol and 1-Naphthol increased more than that of single component system, but for Quinoline the effective solid diffusivity decreased.
