Introduction: Volatile organic compounds are the most common pollutants in the air, and among them, toluene is the most common form, which is toxic resulting in liver and kidneys damages. Regarding the fact that this compound is widely used in various chemical industries, implementing an efficient method for controlling its concentration is of great importance. The comparative survey of the cap...
Approximately 10-20% of the total dyes in the world is consumed in the textile industry. The present study aimed to investigate the photocatalytic activity of zinc oxide nanoparticles (ZnO) immobilized on synthetic activated carbon in the removal of the acid blue 113 dye from aqueous solutions. This experimental study was conducted in a photo-reactor with the useful volume of one liter. The eff...
Background and Objectives: The disposal of waste tires has become an increasingly important issue worldwide in recent years. Tires not only take up large amounts of valuable landfill space, but also create fire hazards and provide a refuge for disease- carrying creatures. The goal of this study was to produce activated carbon from scrap tires .Adsorption of Acid Black1 (AB1) in aqueous solutio...
Background & objective: The presence of natural organic matter in water sources creates various problems, especially in common water treatment process. These compounds cause unfavorable taste and odor in water and are among the most important precursors of water disinfection by-products. This study was carried out to evaluate the efficiency of activated carbon (AC) and activated carbon modified...
Background and Objectives: Because of toxical and hazardous properties of hexavalent chromium (Cr(VI)), its removal by an economical and efficient method is necessary. The use of activated carbon, as an adsorbent, is a common and effective method for hexavalent chromium removal. Thus the aim of this study was to produce granular and powdered activated carbon form Peganum Harmala and compare the...

In this research, two carbon structures silica nanohybrids Pickering emulsions were prepared. Graphite and activated carbon were carbon allotropes with different morphologies of laminar and spherical, respectively. The effect of carbon morphology investigated on the related silica nanohybrids Pickeringemulsions for C-EOR. Therefore, nanohybrids were prepared with graphite and activated carbon t...
the used activated carbon was derived from pine-cone and was used for the removal of acid black 1(ab1) and acid blue 113(ab113) dyes. a batch sorption study was carried out in order to obtain optimum isotherm model. the study showed the best fit of the adsorption isotherm data was obtained using the langmuir model for both dyes. the monolayer maximum saturation capacities of ab1 and ab113 dyes ...
