The removal of the dye Crystal Violet (CV) from a aqueous solution (4 ± 0.23 mg/L CV + 2 mg/L NaCl) by the process of electrocoagulation (EC) was performed in two directions. In the first case, the influence of current density (0.016, 0.024, and 0.032 A/cm 2 ; pH = 3.2) was observed, whereas in the second case, the influence of initial pH (3.2, 5.5, and 7.0; i = 0.024 A/cm 2 ) on the removal of CV dye was considered. During the EC process, which lasted 50 minutes, changes in pH, temperature, electrical conductivity, and CV dye concentration were observed. The efficiency of CV dye removal by the EC process is extremely good. At the same time, the dye removal increases with the duration of the process and with the increase of the current density and pH of the solution. Extremely good results were obtained at the highest current density (complete removal after 40 min) and at an initial pH of 5.5 (complete removal after 30 min). During the EC process, anodic and cathodic material is consumed. The consumption of electrode material increases with the increase of current density and pH of the solution, with the influence of current density being more pronounced. The appearance of the electrode surfaces (taken with an light microscope) shows that the anodes dissolve uniformly and locally during the EC process, while the cathodes are mostly subject to uniform corrosion.
