영문 초록

N-doped Titanium oxides were prepared by using urea as a source of nitrogen. The photoactivities of the doped TiO2 were evaluated on the basis of degradation of humic acid in aqueous solutions with different light sources, ultraviolet lamp, fluorescent lamp and solar light. XRD analysis was conducted to identify the crystal structure of the synthesized photocatalysts. N-doped TiO2 and pure-TiO2 was anatase type. SEM results showed that spherical particles were formed, which are the characteristics of the anatase form. N doped TiO2 showed higher UV254 decrease ratio and DOC removal ratio compared to pure-TiO2. The humic acid degradation reaction using the UV-A lamp and UV-C lamp was assigned to pseudo-first order reaction. For solar light, only pure-TiO2 and N-TiO2 exhibited the pseudo-first order reaction.
