摘要
以活性炭负载二氧化钛为光催化剂,通过微波和紫外光协同TiO_(2)/AC降解废水中的苯胺,考察反应时间、微波功率,紫外光、以及两者协同等对苯胺降解率的影响。结果表明,微波和紫外光协同对苯胺的降解效果较好,180 min后基本达到平衡,微波400 W为最佳反应功率。在此条件下,TiO_(2)/AC对100 mg/L的苯胺废水的去除率可达71.2%。微波辐射联用使光催化剂的降解性能有了明显提高,去除率相较于单独使用微波和紫外光上升了28.29%和76.94%。
The degradation capacity of TiO_(2)/activated carbon to aniline wastwater was discussed.And the content of aniline in water was measured by spectrophotometric method.The effects of degradation time,microwave power,UV and the combination of the two were evaluated.The results showed that the degradation rate of TiO_(2)/AC on aniline in water was better.It took 180 min to reach the degradation equilibrium with a high degradation rate,the best reaction power microwave power is 400 W.Under these conditions,the removal rate of 100 mg/L aniline wastewater could reach 71.2%.The degradation rate of photocatalyst has been significantly improved with microwave radiation,compared with microwave and UV alone,the removal rate increased by 28.29%and 76.94%.
