Effect of trichloroisocyanuric acid on the corrosion resistance of residential water pipes

摘要

The aim of the present study is to assess the effect of one emergency disinfectant (trichloroisocyanuric acid) on the corrosion resistance of different materials used in residential distribution pipes (copper, lead, and galvanised iron). Corrosion in residential distribution systems may cause several problems, such as pipe breaks or water quality deterioration. Therefore, it is interesting to study the effect of disinfectants used in drinking water on the corrosion of metallic pipes. Potentiodynamic curves were carried out for copper, lead, and zinc in trichloroisocyanuric acid solutions at different concentrations at 25 °C. According to the results, the presence of this disinfectant increases the corrosion rate of metallic pipes.
