An Extension of HPA

When we were unsuccessful with the oxidation of oxybenzone both enzymatically and chemically, we turned to HPA for chemical oxidation.

Making the Samples For Chemical Oxidation

2 mM HPA Buffer Stock Solution

Dissolved 30 mg of HPA in 100 mL of ph 5 buffer solution.

Potassium Permanganate Stock Solution

Preparing the final samples

Measured out 5 mL of the 2 mM HPA stock solution into 4 different scintillation vials. Added potassium permanganate solution in increasing concentrations to each vial (6 microliters, 12 microliters, 18 microliters, and 24 microliters).
