Production of activated carbon from the fruits of the Xanthium spinosum plant by Chemical treatment with potassium hydroxide and determination of its physical and adsorption properties

Abstract

   The purpose of this study is to prepare activated carbon with good adsorption properties that can be used in water and air purification. Activated carbon was prepared from the fruits of the Xanthium spinosum plant by chemical treatment with different proportions of potassium hydroxide. Its physical properties (density, moisture, ash) and adsorption properties were measured by adsorption of methylene blue dye as well as iodine for all prepared samples. During the results of the adsorption of methylene blue dye and iodine, the two best models (S3, S4) were taken and the surface area and pore volume were measured through BET examination. This examination showed that the model (S3) had the largest surface area and also the largest pore volume, and these measurements were completely consistent with the adsorption properties in terms of the adsorption of methylene blue dye and iodine for the models (S3, S4).
