Adsorption Desorption Behavior of Water Soluble Film Persistent Corrosion Inhibitor

Water based corrosion inhibitors have been found that provide longer treatment lives and better protection than similar inhibitors in oil-based formulations. In this paper conventional film persistency tests are presented on a water soluble film persistent corrosion inhibitor. The conventional tests allow comparative evaluation of different corrosion inhibitors. Langmuir adsorption and desorption has been recently used to form a method of evaluating the impact of the loss of availability of a corrosion inhibitor. The adsorption-desorption analysis allowed quantitative assessment of loss of availability. In this paper these studies will be continued on a water soluble corrosion inhibitor that has been previously characterized as film persistent in conventional laboratory tests and field experience. The values of adsorption and desorption will be compared with values with a corrosion inhibitor that is not used in batch treatments. The work will aid quantitative laboratory assessment of film persistency.
