Abstract
The modified organic wastes of the caprolactam are investigated by potentiodynamic and impedance technique as corrosion inhibitor of carbon steel in 20 mass % hydrochloric acid solutions. It is shown that the investigated inhibitor retards mainly anodic reaction. The corrosion process is simulated by a parallel circuit of constant phase element and the corrosion resistance connected in series with the solution resistance. The inhibition efficiency reaches 92 ... 93 % at 1 mass % concentration of inhibitor.
