研究了紫外/过氧化氢（UV/H2O2）工艺对直线型烷基苯磺酸盐（LAS）的降解作用。在波长222或254 nm的紫外光的准直光束实验中，h2o2浓度升高时，LAS的降解速度更快。降解行为随光源波长的变化而变化。此外，在管式反应器中进行的降解实验结果表明，UV/ h2o2工艺的反应速度比纯UV工艺快。
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 H2O2concentrations. 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/H2O2process than in the UV-only process.
