摘要
简述TiO_2光催化反应的原理,总结TiO_2光催化技术对土壤中农药、石油类污染物、抗生素等有机物的光催化氧化降解,以及对土壤中一些无机化合物和重金属的光催化氧化还原处理,并提出其未来的发展方向是与其他高级氧化技术、微生物修复技术的协同效应,以及TiO_2光催化降解活性与土壤中污染物分子结构的关系。
The principle of TiO2photocatalytic reaction was described briefly.Both organic compounds in soil including pesticide residues,petroleum pollutant and antibiotic occurred photocatalytic oxidation degradation reaction and inorganic compounds and heavy metal occurred photocatalytic reduction treatment,making use of TiO2photocatalytic oxidation technology were summarized.Additionally,it was proposed that its synergistic effects with other advanced oxidation process,bioremediation technique and relationship between photocatalytic degradation activity and the molecular structure of contamination were its future developing direction.
