1. Dissolution of APV in water: APV is first dissolved in water to form a homogeneous solution. The ratio of APV to water should be 1:1.
2. Acidity Adjustment: The pH of the solution must be adjusted to a range of 4-5.5 by the addition of an acid.
3. Oxidation: The solution is then oxidized with hydrogen peroxide to form H2O2-APV. The reaction is usually carried out at room temperature.
4. Filtration: The H2O2-APV solution is then filtered to remove any insoluble impurities.检验科工作制度

7. Drying: The H2O2-APV is then dried in an oven at a temperature of 50-60°C until it becomes dry to the touch.
8. Storage: The dried H2O2-APV is then stored in an airtight container for future u.
