The classical methods for measuring hydrogen peroxide concentrations are through direct measurement of the absorbance at 240nm of the H 2O 2 molecule, or through reaction of the peroxide with ferrous iron, monitored via a subsequent reaction with the dye xylenol orange. A variety of other methods are also available.

How do you test the activity of hydrogen peroxide?
Add one drop of hydrogen peroxide and look for bubbles. Bubbles are a positive result for the presence of catalase. If no bubbles form, it is a negative result; this suggests that the organism does not produce catalase. Dispose of the slide in a slide disposal bin and any toothpicks in a biohazard bin.
Does hydrogen peroxide react with urine?

Is hydrogen peroxide safe to use everyday?
Hydrogen peroxide is safe for most people if they use it correctly. However, the compound can be harmful if a person uses it too often or if the concentration is too strong. People should never gargle with food-grade hydrogen peroxide, which has a concentration of 35 percent.
How do H2O2 sensors work?
Hydrogen Peroxide sensors are amperimetric devices isolated from the water by a peroxide permeable membrane. As peroxide diffuses through this membrane, it comes in contact with an active electrode and is oxidized on the surface. The net effect is that the sensor generates a current proportional to H2O2 concentration.
What does H2O2 do in a reaction?
With certain organic compounds, hydrogen peroxide reacts to form hydroperoxides or peroxides, several of which are used to initiate polymerization reactions. In most of its reactions, hydrogen peroxide oxidizes other substances, although it is itself oxidized by a few compounds, such as potassium permanganate.
