Dynamic testing can well simulate the indoor environment temperature, relative humidity, air exchange and harmful substances release rate and so on, can more reliably reflect the purification performance of scavenging materials in door. Photodegradation of benzenes by UV/active carbon(AC)/TiO₂ has been carried out through dynamic testing methods in this work. The benzenes removal capacities of UV oxidation, AC adsorption and the photodegradation of UV/AC/TiO₂ were systematically investigated. Moreover, the effects of O₂ content and relative humidity on the degradation efficiency of benzenes by UV/AC/TiO₂ has been discussed. The results indicated that moderate O₂ concentration and relative humidity can obvious enhance the degradation of benzenes under 254 nm UV light. Thus, this dynamic testing methods could effectively evaluate the purification efficiency and degradation rate of different scavenging materials, and it has a vital significance for establishing methods which could estimate the property of air cleaner.
