摘要：

Electropolymerization of water soluble lignin derivatives (lignosulfonates) on steel surface is reported. It was noticed from both an appearance of anodic current of lignin oxidation and a subsequent considerable decrease in current at high anodic potentials, and confirmed by the knowledge of lignin oxidative polymerization. Ionic strength affects a potential of lignin oxidation: an increase of KCl concentration ten times (from 0.1 to 1 M) causes a decrease in oxidation potential for 1 V. Lignosulfonate electropolymerization is resulted in corrosion protection of carbon steel, which was more effective compared to the standard commercially available corrosion inhibitor COREXIT SXT-1003.
