The influence of pH value on ozone oxidation reaction

The main influence factors of PH value on the ozone oxidation process are:

1. The oxidizing ability of oxygen itself is related to the PH value. The oxygen atom in the ozone molecule itself has strong electrophilic or proton characteristics and directly shows strong oxidizing performance. The decomposition rate of ozone in water increases with the increase of PH value. If the PH value is increased by one unit, ozone decomposition will be about three times faster, so that the product has more .OH. It can be seen how alkaline conditions produce strong oxidizing .OH important!

2. The physical and chemical properties of organic matter in wastewater are closely related to PH value.

3. The ozone absorption rate has a certain relationship with the PH value. It is generally considered that the absorption under alkaline conditions is better than that under acidic conditions.

4. The change of PH value in the whole ozone oxidation process is mainly manifested in neutral (PH value=7) or alkaline (PH value>7) conditions. PH value shows a downward trend as the oxidation process progresses, the reason is organic matter Oxidized into small molecules of organic acids and aldehydes, therefore, to strengthen the ozone oxidation reaction, the pH value should be adjusted continuously and slightly alkaline.
