Effect of copper oxide on monochloramine decomposition

2021-4-15 · Abstract. Copper oxide (CuO), a common corrosion product found in copper pipes, has been shown to catalyse the decay of different oxidants in drinking water, including chlorine, bromine, iodine, and chlorine dioxide. However, its impact on monochloramine (NH 2 Cl), a disinfectant commonly used in long distribution system worldwide is still unknown.
