An experimental study of indigo carmine removal from aqueous solution by electrocoagulation

This paper presents an experimental study on the removal of Indigo Carmine dye from aqueous solutions using a batch stirred electrocoagulation reactor. The experimental tests were carried out in a discontinuous system provided with steel electrodes. The main purpose was to investigate the effects of the operating parameters, such as pH, initial concentration, electrolysis duration, current density, and electrolyte support concentration, on the...
