Use bicarbonate quenched with ozone. Quenched with saturated sodium sulfite solution to exterminate the remaining hydrogen peroxide, and potassium iodide starch paper is determined whether quenched clean.
Use bicarbonate to quench ozone. The remaining hydrogen peroxide is quenched using a sodium sulphate saturation solution and potassium iodide starch test paper is used to determine whether it is quenched clean.
