Abstract :Studies, about products obtained from agricultural wastes, have increased within the scope of zero waste studies . The olive pomace is produced as a result of olive oil production. In the present study, activated carbon was synthesized using the olive pomace taken from the olive pomace processing plant operating with a three-phase process. The synthesized activated carbon characterization was performed using Scanning Electron Microscope insert ignore into journalissuearticles values(SEM);, Fourier-Transform Infrared Spectroscopy insert ignore into journalissuearticles values(FT-IR);, Brunauer – Emmett – Teller insert ignore into journalissuearticles values(BET);, and X-Ray Crystallography insert ignore into journalissuearticles values(XRD); devices. Olive pomace activated carbon insert ignore into journalissuearticles values(OPAC); was used for the adsorption of dye from an aqueous solution. The adsorption efficiency of the OPAC was investigated. The initial pH value of dye solution insert ignore into journalissuearticles values(6-9);, the amount of activated carbon insert ignore into journalissuearticles values(0.5 and 1.0 g/L);, and initial dye concentration insert ignore into journalissuearticles values(600-1200 mg/L); were optimized. Also, adsorption kinetic and isotherm calculations were evaluated. The optimum parameters were found as the original pH value insert ignore into journalissuearticles values(pH=8); of dye solutions, OPAC amount of 1.0 g/L and the initial concentration of 1000 mg/L. The Langmuir isotherm model and the pseudo-second-order kinetic model were found as the most suitable models. It can be said that the synthesized material can be used at dye removing from wastewater.
