| 摘 要： | 进行了光/Fe(III)体系降解染料罗丹明B水溶液的研究,考察了无机阴离子(Cl-、HCO-3和SO2-4)对罗丹明B光降解的影响。结果表明,当Fe(III)的初始浓度为0.5 mmol·L-1,溶液的初始pH=3.6,经氙灯(λ>290 nm)照射60 min后,罗丹明B(5 mg·L-1)去除率达到91%,而反应105 min时去除率几乎达到100%。Cl-的存在对罗丹明B的降解具有抑制作用,并且浓度越高抑制作用越明显;SO2-4的存在也会降低罗丹明B的去除效率;而HCO-3的存在对罗丹明B的去除率影响不大,且具有一定的促进作用。

| Abstract: | The degradation of rhodamine B (RhB) in aqueous solution containing Fe(III) was studied, and the influence of various anions, such as Cl-, HCO-3 and SO2-4 on the effect of RhB removal was also investigated. The results show that the degradation rate of RhB (5 mg·L-1) is 91% after 60 min with Xe lamp irradiation (λ>290 nm) under the experimental conditions of pH=3.6, Fe3+]0 = 0.5 mmol·L-1 at room temperature. The removal rate of RhB reached almost 100% after 105 min reaction. The photodegradation of RhB in aqueous solution containing Fe(III) is inhibited by the presence of C1-and SO2-4, while the rate of RhB removal is increased slightly in the presence of HCO-3. |
