Abstract
AbstractAdsorption isotherms of various low‐biodegradable aromatic compounds on two different activated carbons were determined experimentally and described by FREUNDLICH‐type isotherm equations. The equilibrium solid loadings derived from the measurements correlate reasonably well with the adsorbent surface areas and show decreasing values in the order 3‐nitro‐aniline ∼ 4‐chloroaniline > 3.5‐dinitrobenzoic acid < phenylurea. Kinetic experiments in a differential column batch reactor were conducted in order to evaluate liquid‐phase mass transfer and intraparticle diffusion parameters. The homogeneous surface diffusion model could be successfully applied for calculating surface diffusivities and predicting experimental concentration/time profiles.
