Abstract: Chlorophenols (CP) represents a group of organic compounds having substituted chlorines attached to phenol ring. These trace organic pollutants represent a major environmental concern, because of toxicity, non-biodegradability, carcinogenic and stubborn properties. The adsorption of 2, 4-dichlorophenol (DCP) by chemically activated carbon of almond shells (CAC-AS) has been studied in the batch setup. Operational parameters like adsorbent dose, pH, and shaking speed were investigated. Langmuir and Freundlich isotherms were employed to calculate adsorption capacity and other sorption features of CAC-AS. The maximum amount of DCP adsorbed was 24.3 mg per gram of activated carbon derived from almond shells. Optimum conditions for DCP uptake were 2.5g adsorbent dose, pH 5 and agitation speed of 200 rpm whereas the concentration of DCP solution was 25 mg/L (50 mL). Results corroborated that almond shells pretreated chemically, can be an excellent low cost adsorbents for removal of DCP from contaminated water.
