Embodiment 1
[0032] use as figure 1 As shown in the device, configure 4 cups of 500mL acetic acid solution containing 100mg / L, respectively add solid superacid catalyst in an amount of 0.4g / L, then add sulfuric acid to adjust the pH to 0, 0.5, 1.0, 1.5, and then add Into the ozone reactor, add hydrogen peroxide at a concentration of 100 mg / L, and pass through ozone.
[0033] The dosage of ozone is 47.6mg / min. At the beginning of the experiment, samples were taken for detection after 30 minutes of reaction.
[0034] Detection method: Acetic acid adopts ThermoFisher Dionex Ultimate3000 high performance liquid chromatography.
[0035] The effect after water sample treatment for 30 minutes is shown in Table 1:
[0036] Table 1
[0037]
Embodiment 2
[0039] use as figure 1 The device shown is equipped with 4 cups of 500mL acetic acid solution containing 100mg / L, and the dosage of solid superacid catalyst is 0.4g / L, and then sulfuric acid is added to adjust the pH to 2, 3, 4, 5, and then Add it into the ozone reactor, add hydrogen peroxide at a concentration of 100mg / L, and pass through ozone.
[0040] The dosage of ozone is 47.6mg / min. At the beginning of the experiment, samples were taken after 60 minutes of reaction.
[0041] Detection method: Acetic acid adopts ThermoFisher Dionex Ultimate3000 high performance liquid chromatography.
[0042] The effect after water sample treatment for 30 minutes is shown in Table 2:
