摘　　要：　在实验条件下,紫外光不能降解20mg/L碱性品红.H2O2能够显著加速碱性品红光化学降解,I-/NO-3能够稍微加速碱性品红光化学降解,Cl-/Br-/SO2-4对碱性品红光化学降解没有影响.Cl-/NO-3/SO2-4对H2O2加速碱性品红光化学降解的作用没有影响,Br-能够稍微抑制H2O2的加速作用,I-能够明显增强H2O2的加速作用.Under experimental conditions, UV light can't degrade 20 mg/L fuchsin basic(FB). H-2O-2 can strikingly accelerate the photochemical degradation of FB, I+-/NO+--3 can slightly accelerate the photochemical degradation of FB, Cl+-/Br+-/SO+{2-}-4 has no effect on the photochemical degradation of FB. Cl+-/NO+--3/SO+{2-}-4 has no influence on the acceleration effect of H-2O-2 on the photochemical degradation of FB, Br+- can slightly inhibit the acceleration effect of H-2O-2, I+- can evidently increase the acceleration effect of H-2O-2.
