What reagent can be used to oxidize phosphite to phosphate?

Everyone, what reagents or processes can be used to oxidize phosphite (PO32-) into phosphate (PO43-)? Can sodium hypochlorite or hydrogen peroxide be used? Can complete oxidation be achieved using these media? Thank you!

It is feasible; add hydrogen peroxide with a concentration of 30% in proportion, at an operating temperature of around 30°C. Phosphite can be oxidized to phosphate 100%.

Hydrogen peroxide is recommended as it does not introduce other impurities.
