The adsorption and photodecomposition of diphenolic acid (DPA) was investigated in the presence of alpha- or beta- cyclodextrins (CDs) and TiO2 suspensions. The adsorption of DPA on TiO2 surface and inclusion complex of CDs and DPA were critical factor in the photocatalytic reaction. Results showed that, the adsorption isotherms of DPA could be plotted with the Langmuir isotherm model, and the max...Show More
This paper investigated the photocatalysis degradation of diphenolic acid (DPA) in the presence of beta-cyclodextrin (beta-CD) under a 30 W UV lamp ( lambdamax=254 nm ). In control experiment, the photodegradation rate of DPA is enhanced 33.5% after 30 min irradiation. The interaction of DPA with beta-CD yielded the formation of inclusion complexes at 1:1 stoichiometric ratio in solution, and beta...Show More
This paper investigated the photochemical behavior of diphenolic acid (DPA) in the presence of beta-cyclodextrin (CD) and TiO2 suspensions under a 250 W metal halide lamp (lambdages 365 nm). The interaction of DPA with CD yielded the formation of inclusion complexes at 1:1 stoichiometric ratio in solution. The irradiation of DPA and TiO2 suspensions in the presence of beta-CD showed that the photo...Show More
Like BPA, bisphenol F (BPF) was used in the production of epoxy resins and polycarbonates and it was shown to be a xenoestrogen. The photodegradation of bisphenol F (BPF) in the presence of algae was investigated under the irradiation of metal halide lamps placed in cooling trap for maintaining constant temperature by water circulation (lambdages365 nm, 250 W). The effect of algae concentration, i...Show More
