H2 O2 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 H2 O2 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。 H2 O2 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 ,H2 O2 还影响到用作光催化剂的 Ti O2 的活性。 H2O2 concentration is one of the important factors affecting the degree of phenol degradation. Experiments show that different concentrations of H2O2 in the phenol degradation process played a major role is not the same. In the degradation of cyclic organic compounds, phenol often appears as a by-product, therefore, the degree of degradation of phenol often also affects the degree of degradation of these cyclic organic compounds. H2 O2 can affect the degradation degree of phenol under photooxidation, photocatalytic oxidation and photoelectrocatalytic oxidation. In the latter two conditions, H2 O2 also affects the activity of Ti O2 used as a photocatalyst.
