The Adsorption of Pentachlorophenol (PCP) on Aerobic Granules

Abstract:

the adsorption of PCP using aerobic granules was studied. The static adsorption experiments were carried out and the Freundlich and Langmuir adsorption isotherms were applied to describe the biosorption processes and the isotherm constants were evaluated. The Freundlich and Langmuir isothermy adsorption equations obtained from the static experients were q=2.04ce0.82 and q=3.47ce /(1+0.56 ce), respectively. Both the adsorption isotherms described the static adsorption behavior of PCP well. Then the Freundlich adsorption isotherm was used to estimate the adsorption of PCP by aerobic granules in the dynamic state. The results showed that the adsorption mainly occurred in the initial periods during the operation of the reactor.
