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) inĀ  aqueous solution as a pollutant by the activated carbon was also investigated.Materials and Methods: Activated carbon was prepared from scrap vehicle tires using a thermo-chemical activation method. The chemical composition and solid structure of prepared activated carbon were analyzed using Scanning Electron Microscopy (SEM) coupled with energy dispersive spectrometry (EDS) and Nitrogen Sas. Micro pore volumes of the sample were determined by the application of the BET and BJH.Results: Predominant composition of prepared activated carbon was C (83.274%) and with area surface of 44.226 and 35.747 m2/gr observed by BET and BJH methods, respectively. Mean pore diameter was 52 nm. The result of this study showed that increasing of initial dye concentration and pH would lead to decrease of adsorption/removal of dye but by increasing of sorbent dosage and contact time, adsorption/removal of dye increased.Conclusion: As the results of present study it can be concluded that the production of the activated carbon from scrap tires, can provide a two-fold environmental and economic benefit; a recycling path is created for scrap tires of vehicles, and a new suitable adsorbent is produced for pollutants removal.
