Abstract
Removal of catechol and resorcinol from aqueous solutions by adsorption onto high area activated carbon cloth (ACC) was investigated. Kinetics of adsorption was followed by in-situ uv-spectroscopy and the data were treated according to pseudo-first-order, pseudo-second-order and intraparticle diffusion models. It was found that the adsorption process of these compounds onto ACC follows pseudo-second-order model. Furthermore, intraparticle diffusion is effective in rate of adsorption processes of these compounds. Adsorption isotherms were derived at 25 ° C on the basis of batch analysis. Isotherm data were treated according to Langmuir and Freundlich models. The fits of experimental data to these equations were examined.
