Reactive and acid colourants are two important classes of textile dyes. Cheap, easy-to- use and non-pollutant new treatment methods have been gaining importance for removal of colourants from drain water since the physical and chemical technics such as adsorption, coalugation-floculation, filtration, oxidation, ozonization, electrochemical claeaning are expansive and have high investment and operating costs, also, they produce new pollutions. Active carbon is a material which is frequently used for removal of colourants from environment owing to its properties like having vide surface area, containing micro, meso and macro pores. In this study, Zivzik pomegranate from Siirt district of TURKEY was used as active carbon and it was prepared with ZnCl2 by chemical activation. Since measurement of surface area determines amount of colourant it can remove, surface area was measured by BET and removals of Methylene Blue and Crystal Violet were investigated. In our study, adsorptions to active carbon at three different temperatures of 25°C, 35°C and 45°C for the colourants of Methylene Blue and Crystal Violet were evaluated as a function of initial colourant concentration of 800 mg/L graphically and thermodynamical parameters were investigated. As a result, it was found that adsorption process is endothermic and occurs spontaneously (i.e. a physical process). Key words: Active carbon, Colourant, Adsorption, Thermodynamic
