Abstract
L'invention concerne une électrode pouvant être utilisée en relation avec un électrolyte. L'électrode comprend une composante d'électrode primaire comportant un matériau conducteur poreux et une composante d'électrode secondaire en contact électrique avec la composante d'électrode primaire. La composante d'électrode secondaire 50 comprend une surface métallique qui est normalement conductrice lorsque l'électrode fonctionne comme cathode et qui, alternativement, peut passer dans l'état non conducteur lorsque l'électrode fonctionne comme anode pour revenir dans l'état conducteur lorsque l'électrode est de nouveau utilisée comme cathode L'invention s'applique notamment à l'extraction de métaux dilués dans des effluents industriels ou des eaux résiduaires.
