光催化降解二苯胺的研究

Study on Photo Catalytic Degradation of DPA

实验研究了α-Fe2O3光催化降解二苯胺,探讨了催化剂浓度、溶液的初始浓度、pH值因素对降解效率的影响。研究表明,在二苯胺初始浓度为30 mg/L,半导体浓度为0.2 g/L,pH=8.5的条件下二苯胺的降解效率可达94%。

Degradation of DPA was investigated when α-Fe2O3 was used as the photocatalyst. The effect of photocatalyst concentration, initial concentration, pH value, on the rate of DPA photocatalytic degradation was studied. The results showed that photocatalytic degradation rate can reached 94% under the best condition that initial concentration of DPA was 30 mg/L, photo catalyst concentration was 0.2g/L, pH=8.5.
