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 purpose of this project was to develop 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).The study found that the titanium oxalate method is an effective method for detecting hydrogen peroxide in the presence of chloramine and is suitable for use with AOPs.
