PMS (Oxone?) decomposes to O2, which is seen as bubbles. You do not need to quantify H2O2 to know what is in the bubbles.

Thank you very much Dr. Yurii V Geletii

Dear Aimal Khan,

Evolution of concentration of peroxomolybdate complex is a great way how to determine H2O2 in the complicated matrices (e.g. in your case, double oxidant system). Please see:
