In this study, we investigated the degradation of linear alkylbenzene sulfonate (LAS) by an ultraviolet/hydrogen peroxide (UV/H2O2) process. In a collimated beam experiment with UV light of wavelength 222 or 254 nm, faster LAS degradation rates occurred at elevated H2O2 concentrations. The degradation behavior varied with the wavelength of the light source. Furthermore, according to the results of a degradation experiment in a tubular reactor, the reaction rate was faster in the UV/H2O2 process than in the UV-only process.

UV/H2O2法降解直链烷基苯磺酸盐

在本研究中，我们研究了通过紫外线/过氧化氢 (UV/H2O2) 工艺降解线性烷基苯磺酸盐 (LAS)。在使用波长为 222 或 254 nm 的紫外光进行的准直光束实验中，在 H2O2 浓度升高时发生更快的 LAS 降解速率。退化行为随着光源的波长而变化。此外，根据管式反应器中的降解实验结果，UV/H2O2 工艺中的反应速率比纯 UV 工艺更快。
