| 摘要: |
| 在紫外光作用下,采用静态方法研究氧化剂(H2O2、KIO4)和阴离子(Cl-、Br-、SO42-、Ac-)对4-硝基酚光化学降解的影响。结果表明,紫外光不能降解20mg/L4-硝基酚。H2O2能够明显加速4-硝基酚光化学降解,KIO4能够显著加速4-硝基酚光化学降解,Cl-、Br-、SO42-、Ac-对4-硝基酚光化学降解没有影响。Cl-、Br-、Ac-稍微抑制H2O2的加速作用,SO42-对H2O2的加速作用没有影响。Cl-、SO42-对KIO4的加速作用没有影响,Br-、Ac-能够稍微抑制KIO4的加速作用 |

| Abstract: |
| Under the UV-light,effects of oxidants and cations on the photochemical degradation of 4-nitrophenol 4-NP were studied by static method.The results showed that 20 mg/L 4-NP could not be degradated by UV-light,H2O2 can evidently accelerate the photochemical degradation of 4-NP, KIO4 can strikingly accelerate the photochemical degradation of 4-NP,Cl-、Br-、SO42-、Ac- have no influence on the photochemical dgradation of 4-NP.Cl-、Br-、Ac- can slightly inhibit the acceleration effect of H2O2,SO42- has no influence on the acceleration effect of H2O2. Cl-、SO42- have no influence on the acceleration effect of KIO4, Br-、Ac- can slightly inhibit the acceleration effect of KIO4. |
