The adsorptive capacity of phenol, chlorophenol, chlorobenzene and ethylbenzene by inert microbial biomass was studied. Desorption and reversibility of adsorption processes were also investigated. The experimental results suggest that the adsorption process of liquid organic compounds can be expressed by the Freudlich Adsorption Isotherm. Sorption capacity is strongly correlated to molecular properties such as water solubility and octanol/water partition coefficient. The combination of lower solubility and higher octanol/water partition coefficient favors the adsorption by microbial biomass. Desorption studies indicated that there are considerable amounts of desorption of phenol and chlorophenol but not chlorobenzene and ethylbenzene. Adsorption by microbial biomass is not completely reversible.
