摘要
研究了双酚F在β-环糊精存在的TiO2光催化体系中的光降解行为，结果表明：双酚F能与β-环糊精形成1：1稳定的包结物，其包结常数为6．33×10^3L/mol，β-环糊精可以使双酚F的光催化降解效率可以提高21％，同时研究了双酚F光降解的动力学规律及pH、β-环糊精浓度、双酚F初始浓度对双酚F的光催化降解的影响。β-环糊精对双酚F光催化降解的强化作用源于β-环糊精促进双酚F在TiO2表面的吸附。
TiO_2 photocatalytic degradation of bisphenol F(BPF)in the presence ofβ-cyclodextrin(β-CD)was investigated.Results showed that BPF can form 1:1 inclusion complex withβ-CD,with formation constant of 6.33×10~3L/mol.β-CD can increase photodegradation efficiency by about 21%.The effect of pH value,initial concentration of BPF and concentration ofβ-CD as well as kinetics analysis was studied, and the enhancement of photodegradation of BFP mainly resulted from the enhancement of adsorption of BPF on TiO_2 surface.
