Electrochemical behaviour of metals in micellar medium and in water—tributylphosphate emulsions. Application to electrowinning of metals in waste water—I. Micellar medium

The inhibition of copper(II), nickel(II), cadmium(II), lead(II), cobalt(II), zinc(II) reduction by a non-ionic surfactant is studied in NaClO₄ as a non-complexing medium and in KSCN as a complexing medium. The magnitude of inhibition of these reactions appears very different according to pH in the perchlorate medium. In the thiocyanate medium, it seems that the stability of the complex has a very significant role in the inhibition process.
