H2O2在苯酚降解过程中的作用研究

H2O2浓度是影响苯酚降解程度的重要因素之一。实验表明，不同浓度的H2O2在苯酚降解过程中所起的主要作用也不相同。在环状有机物的降解过程中，苯酚往往作为副产物出现，因此，苯酚的降解程度也往往影响到这些环状有机物的降解程度。H2O2在光氧化、光催化氧化和光电催化氧化的条件下均能影响苯酚的降解程度。在后两种条件下，H2O2还影响到用作光催化剂的TiO2的活性。

Study on the Function of H2O2 during the Phenol Degrading Process

The concentration of hydrogen peroxide is one of the most important factors affecting the degree of phenol degradation. Through experiment data, this paper tries to expand that the main function of hydrogen peroxide with different concentration is quite different during the phenol degrading progress. Phenol always appears as the by-product in the course of compound degrading process, so that its degradation degree always affects the degradation degree of these compounds. Hydrogen peroxide can affect the degree of phenol degradation under the conditions of photooxidation, photocatalysis-oxidation and photoelectrocatalysis-oxidation. And it can also affect the activity of TiO 2 that used as the photocatalyst under the last two conditions.
