Modification of the electrochemical behaviour of the cadmium electrode.by benzotriazole (BTA) has been extensively studied by potentiodynamic experiments. BTA is found to react with metallic cadmium to form surface fllms that provide large electrochemkally active surface areas. A complexation phenomenon, as detected by IB spectra, is suggested.
Experimental
Cyclic voltammetry was performed using a Wenking potentiostat (Model ST 72) in comunction with a voltage scan generator (Model VSG 72).

The anodic dissolution of indium amalgams in alkaline solutions follows a three-stage oxidation process, similar to the process in acidic solutions . The anodic films produced on indium amalgams are amorphous indium hydroxide . They are similar to anodic mercuric oxide and thallous chloride films i
