Abstract
Coal fly ash, a solid waste from thermal power stations was used to su ccessfully remove 2,4-dimethyl phenol by adsorption from aqueous solut ions. The rate of adsorption follows first order kinetics before attai ning equilibrium. Both diffusional and kinetic resistances affect the rate of adsorption and their relative effects vary with operating temp eratures. Equilibrium adsorption data satisfied both Langmuir and Freu ndlich isotherms.
