Nowadays, the damage of the environment quality has reached alarming levels requiring severe measures for stopping this process. In order to harmonise with the maximum admitted concentrations (MAC) of heavy metal ions (HMIs) in the discharged effluents, the electrochemical procedures represent a clean, flexible and efficient alternative of decontamination. In this context, the present paper describes the results of our researches concerning the electroextraction of heavy metals from synthetic diluted solutions. Starting from simple or complex solutions with initial HMI contents of 10 ppm (parts per million), the MAC can be reached after 90 min. of electrolysis in a continuous flow electrochemical reactor equipped with a three-dimensional (3D) electrode made of reticulated vitreous carbon.
