Methods for the Detection of Residual Concentrations of Hydrogen Peroxide in Advanced Oxidation Processes (TC with WB)

Advanced oxidation processes (AOPs), coupling either ultraviolet (UV) irradiation or ozonation in the presence of hydrogen peroxide, are advanced treatment techniques that have been installed by several utilities to meet California Department of Public Health regulations. Of prime importance in monitoring the performance of AOPs is the ability to accurately measure residual hydrogen peroxide concentrations. The project developed a laboratory method for reliable quantification of hydrogen peroxide in the 0.5- to 5-mg/L concentration range that is effective in a natural water matrix as well as in the presence of combined chlorine (chloramine).
