The oxidation of oxybenzone was attempted with a reaction of oxybenzone, hydrogen peroxide, and horseradish peroxidase.
Making the Samples
Our actual samples to be tested required the making of a 2 mM oxybenzone pH 5 buffer stock solution, a hydrogen peroxide stock solution, and a horseradish peroxidase solution.
2 mM Oxybenzone Buffer Stock Solution
Combined 50 mL of dioxane, 50 mL of pH 5 buffer solution, and 45.7 mg of oxybenzone in a bottle. Added the oxybenzone to the dioxane, and then added the buffer solution.
Hydrogen Peroxide Stock Solution
Measured 5 mL of water into a scintillation vial. Added 283 microliters of 30% hydrogen peroxide to the water. This provided a hydrogen peroxide solution of about 0.413 M.
Horseradish Peroxidase Stock Solution
Preparing the Final Samples
Measure out 5 mL of the 2 mM oxybenzone buffer stock solution into 4 different scintillation vials. Added hydrogen peroxide solution in different amounts to each vial (6 microliters, 12 microliters, 18 microliters, and 24 microliters). Add 10 microliters of horseradish peroxidase solution to each vial.
