Abstract

The study was designed to investigate optimal conditions of the activated carbon preparation from date pits using zinc chloride solution as a chemical activator. Activation conditions varied were inert (N₂) gas flow rate, impregnation ratio, activation temperature and time. Factorial analysis and analysis of variance were implemented to study the mutual influence of these conditions on the surface properties of the activated carbon samples prepared. It was found that the iodine number and the surface area are influenced by all four activation parameters. In the same time, the methylene blue number is only influenced by the activation temperature and time. The optimal conditions for the preparation of the activated carbon from date pits were found to be 200 mL min⁻¹ of nitrogen gas flow rate, 25% zinc chloride solution concentration, 800 °C activation temperature and 3.0 hours of activation time. These activation conditions allowed to achieve 407.150 mg g⁻¹ of iodine number, 25.38 mg g⁻¹ of methylene blue number and 390.50 m² g⁻¹ of the surface area.
