Adsorption has been recognized as an effective method for removal of pollutants from water(1,2). Antibiotics belong to a group of antimicrobial compounds commonly used to treat the disease caused by microorganisms, however, the biodegradadibility of antibiotics is difficult, resulting in their nearly breakthrough in traditional wastewater treatment plants. Adsorptive removal by porous materials provides an option for removal of antibiotics in the effluent from waste water treatment plant or other water bodies. Till now, most studies used non-renewable adsorbents for antibiotics adsorption(3,4). Adsorption has been shown to be the most promising option for all these non-biodegradable organics for the removal of aqueous steams, activating carbon being the most common adsorbent for this process due to its effectiveness and versatility. Although activated carbon in granular or powdered form has a good capacity for the adsorption of organic molecules, it suffers from a number of disadvantages. Activated carbon is quite expensive and the higher the quality the greater the cost(5,6), however due to the high cost of activated carbons, the scope of many adsorption studies has been focused on deriving cheaper adsorbents from waste materials. Thus, cheap and effective adsorbents hav been developed from various waste materials such as chitin and chitosan(7) pomelo (Citrus grandis) pee (8), rice husk(9) sunflower seed hull
