摘要
本研究的目的是利用改进的光解反应器组件，研究光催化降解废水中染料的去除。它的效率更高，染料降解速度也很快。采用紫外/可见分光光度法对反应进行监测。比较了不同催化剂对染料的降解，发现染料的降解遵循一级动力学。亚甲基蓝最佳提取结果为t(1/2)=4 min, k = 0.4471 min-1, R2 = 0.9650;酒黄石最佳提取结果为t(1/2)= 1.2 min, k = 0.9723 min-1, R2 = 0.9980;翠绿最佳提取结果为t(1/2)= 0.8 min, k = 0.9716min-1, R2 = 0.9938。因此，它可以有效地在更大的范围内使用。关键词:亚甲基蓝，酒黄石，艳绿，光解，降解
Rapid photocatalytic degradation of methylene blue, tartrazine and brilliant green dyes by high-flux UV irradiation photolysis reactor
The aim of this work was to investigate the removal of dyes from wastewater by photocatalytic degradation using a modified assembly of photolysis reactor. It was more efficient and dye degradation occurred very fast. UV/Visible spectrophotometry was used to monitor the reaction. The degradation of dyes with different catalysts was compared and found to follow first-order kinetics. The optimal result for Methylene Blue was t(1/2)=4 min, k = 0.4471 min-1, R2 = 0.9650, for Tartrazine - t(1/2) = 1.2 min, k = 0.9723 min-1, R2 = 0.9980 and for Brilliant Green - t(1/2) = 0.8 min, k = 0.9716 min-1, R2 = 0.9938. So, it can be efficiently employed on a larger scale. Keywords: Methylene Blue, Tartrazine, Brilliant Green, Photolysis, Degradation.
