Abstract:
The adsorption characteristics of phenol, p-chlorophenol and p-nitrophenol in wastewater by activated carbon fiber (ACF) were studied. The surface properties of ACF were characterized by scanning electron microscopy (SEM). The thermodynamic characteristics and mechanism of phenol, p-chlorophenol and p-nitrophenol adsorption on ACF were investigated by using the bottle-point technique. The results showed that the adsorption speed was fast, and ACF had good adsorption properties when pH < 7. On the same condition, the order of removal efficiency were: phenol (87%) < p-chlorophenol (96%) < p-nitrophenol (99%). All the adsorptions are physical adsorption, and the adsorption process were spontaneous exothermic reaction. All the adsorption isotherms can be well represented by Dubinin-Radushkevich equation and the sorption process were spontaneous exothermic reaction.

Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
