Abstract: A method for recovering a corrosion inhibitor from a water system includes treating a water stream of the water system that includes the corrosion inhibitor to selectively recover the corrosion inhibitor from the water stream. The method may include introducing the recovered corrosion inhibitor back into the water system. The corrosion inhibitor may be selectively recovered by applying a predetermined voltage to the electrochemical system to change an oxidation state of the corrosion inhibitor, the predetermined voltage corresponding to an oxidation reduction potential of the corrosion inhibitor.
