Evaluation of Hydrogen Peroxide Chemical Quenching Agents following an Advanced Oxidation Process

AbstractFree chlorine, bovine catalase, sulfite, and thiosulfate were examined as methods for quenching residual hydrogen peroxide after advanced oxidation treatment of water for subsequent laboratory analysis. The challenges and advantages of each method are presented to help inform researchers and...

Summary:AbstractFree chlorine, bovine catalase, sulfite, and thiosulfate were examined as methods for quenching residual hydrogen peroxide after advanced oxidation treatment of water for subsequent laboratory analysis. The challenges and advantages of each method are presented to help inform researchers and practitioners. Quenching hydrogen peroxide with free chlorine is determined to be a better alternative for disinfection byproduct testing, while bovine catalase is a preferred quenching agent for toxicity testing and mass spectrometry analysis.
