The degradation of acid orange 7 dye (AO7) was studied using a 1 L semi-batch tank stirred glass reactor for performing three different photochemical processes (photoperoxidation, Fenton, photo-Fenton). A commercial low pressure lamp was used for irradiation of samples. The advancement of degradation was monitored by measurement of color reduction, UV-spectra, HPLC-UV and COD. The obtained results showed that the photo-Fenton treatment was the most effective for the degradation of AO7.
使用一个1升的半间歇式搅拌玻璃反应器研究了酸性橙7染料(AO7)的降解情况,以进行三种不同的光化学过程(光过氧化、芬顿、光芬顿)。使用商用低压灯对样品进行照射。通过测量颜色降低、紫外光谱、高效液相色谱-紫外和化学需氧量来监测降解进程。所得结果表明,光芬顿处理对AO7的降解最为有效。
