ABSTRACT
Physical or chemical processes can enrich surface functional groups of activated carbon. EDTA grafting was applied to the carbon surface using a chemical treatment in this study. In this way, while there was no significant change in the surface area of the carbon, the Golden Yellow (GY) removal performance increased. The changes caused by EDTA grafting on the carbon surface have been revealed using various methods. Environmental conditions affecting the adsorption process were statistically investigated using Central Composite Design (CCD). Different equations were used to determine the stability, capacity, and mechanism of the GY removal with activated carbon and EDTA grafted carbon.
