Abstract
The aim of this work is to prepare activated carbon from date seeds to treat wastewater. The study of the characteristics of activated carbon from El-Oued dates gave the following results: surface area (125.86m2/g), pore volume (0.039cc/g), pore size (16.25mm), microspores surface area (92.28 m2/g), the external surface (33.57 m2/g), methylene blue index (13.6 mg/g), iodine number (735.2 mg/g) and amount of functional groups (4.10-2 mol/g). The best conditions for the removal of organic pollutants are: contact time (5 min), stirring speed between 200 and 300 rpm and a pH below 5 or above 8. The removal of organic pollutants in wastewater from El-Oued region prepared by the charcoal has led to very significant abatement rate: COD (86.9%) and BOD5 (87.55%).
