How can I minimize H₂O₂ decomposition?

Commercial grades of H2O2 contain stabilizers designed to minimize its decomposition during normal transportation and storage. In some cases, these stabilizers also may improve the performance of H2O2 in the application. Therefore, you should perform the following:

1. Match the H2O2 grade to your application.
2. Select and prepare construction materials according to manufacturer guidelines (see Safety and Handling Guidelines). The procedure of passivating the piping assembly with dilute nitric acid removes surface contaminants and imparts a protective oxide layer to the surface metal.
3. Limit exposure of the product to environmental stresses such as heat, sunlight or dust.
4. Control the degree of contamination introduced by carrier (or dilution) waters, or even the process water into which it is being applied.
