摘要
紫外光与过氧化氢水溶液相结合的光化学氧化方法是目前被广泛应用的高级氧化技术。由于其具有连续辐照光谱,故在这两种高级氧化技术的应用中,中压汞灯被认为较低压汞灯有更高的效率。因此,将基于实验室前期开发的中压细管流紫外反应器来研究中压紫外结合过氧化氢对水中对氯苯甲酸的降解,并探讨不同因素对降解反应的影响。试验结果将与低压汞灯试验进行对比,从实验和理论的角度揭示中压汞灯效率较高的原因。
The photochemical oxidation method combining UV light and aqueous hydrogen peroxide is an advanced oxidation technique.Because of its continuous irradiation spectrum,medium pressure mercury lamp is considered to have higher efficiency than low pressure mercury lamp in the application of these two advanced oxidation techniques.Therefore,the degradation of chlorobenzoic acid in water was studied in the early laboratory,and the influence of different factors on the degradation reaction was explored.The test results would be compared with the low pressure mercury lamp test to reveal the reasons for the higher efficiency of the medium pressure mercury lamp from the experimental and theoretical perspective.
