The effectiveness of virgin and regenerated activated carbons was established for crystal violet removed from aqueous solutions. Granular activated carbon, WDex, saturated with the dye was regenerated using classic or modified Fenton’s reagent, Fe 2+/H2O2 and Fe2+/Ox, respectively. The application of modified Fenton’s reagent resulted in the formation of hydrogen peroxide directly in the regeneration solution. The study was conducted under static and dynamic conditions. The sorptive capacities of virgin and regenerated WDex activated carbons for crystal violet were reported to be similar (approximately 42 mg/g). The results of the dynamic sorption show that under the predetermined conditions the regenerated activated carbons were better sorbents. The amount of dynamic sorption was approx. 17.6 g/dm3. The longest breakthrough time (3970 min) and the longest saturation time (11 600 min) were observed for the carbon bed regenerated with modified Fenton’s reagent.
