Abstract
Traitement des électrodes par nettoyage. On débarrasse l'électrode des produits de corrosion et de l'amiante, en la mettant en contact avec une solution de nettoyage aqueuse contenant un inhibiteur d'oxydation, de l'acide chlorhydrique et une source d'acide fluorhydrique. On peut aussi traiter par voie électrolytique la surface métallique nettoyée à l'aide d'un acide hydroxy phosphonique organique Application à l'électrolyse des chlorures alcalins.
