INHIBITION OF (NH2)2CS ON ANODIC DISSOLUTION OF COPPER IN HALIDE SOLUTIONS
|
Abstract:
Inhibition of (NH 2) 2CS on anodic dissolution of copper in neutral NaF,NaCl,NaBr and KI solutions was investigated by potentiostatic steady-state polarization and transient-state polarization methods.The inhibition mechanism of (NH 2) 2CS was interpreted in detail by comparing the electrochemical behaviors of copper in halide solutions with and without (NH 2) 2CS.In addition,the effect of scan rate on peak current and potential was studied when a film CuX was formed,and the mechanism of dissolution of copper in halide solutions was also discussed.
