| 摘 要： | 在TiO2/SiO2/Fe3O4物化特性的研究中,通过测定方法的改进首次获得光照反应阶段TiO2/SiO2/Fe3O4吸附量与溶液残余量间的定量关系(以苯酚为例,结果表明:在光照及无光照条件下TiO2/SiO2/Fe3O4遵循不同的吸附规律,以后者取代前者存在明显缺陷;揭示了凝聚现象是导致TiO2/SiO2/Fe3O4光活性降低的主要原因。

| Abstract: | For the first time,the adsorptive amounts of organic compounds on TiO2/SiO2/Fe3O4 in UV-irradiation process and adsorption expression between TiO2/SiO2/Fe3O4 and residual organic compounds were obtained by a modified menstruation,taking phenol as an example.Results showed that the specific adsorption of compounds on TiO2/SiO2/Fe3O4 during the irradiation period was different from that during the dark period.The prime reason for deactivation of TiO2/SiO2/Fe3O4 in process was particle aggregation. |
