Abstract
Corrosion is a complex series of oxidation/reduction reactions between at the water-metal surfaces and materials in which the water is stored or transported. With respect to the corrosion potential of drinking water, the primary concerns include the potential presence of toxic metals, such as lead and copper; deterioration and damage to the household plumbing, and aesthetic problems such as stained laundry, and bitter taste. This study was performed to evaluate the effects of corrosion inhibitors on corrosion rates, Fe and Cu release concentration in water distribution pipes. Decrease of corrosion rates were strongly related to phosphate corrosion inhibitors. Considering that typical corrosion processes consists of a series of electrochemical reaction at the metal surface in contact with water, corrosion rates were positively correlated with Fe release.
