摘要: This study evaluated the application of a continuous-flow photocatalytic reactor for control two mobile-derived pollutants, methyl-tertiary butyl ether (MTBE) and naphthalene, present at in-vehicle levels. Variables tested this included hydraulic diameter (HD), stream flow rate (SFR), relative humidity (RH), feeding type (FT). The fixed parameters contaminant concentration, ultraviolet light source, weight TiO2. In all experimental conditions adsorption process reached equilibrium within 30 to 180 min target compounds, outlet concentrations oxidation (PCO) while operating steady state 60 min. degradation compounds was dependent on RH, HD, FT, or SFR. PCO system exhibited high (up nearly 100% certain conditions) mineralization efficiencies suggesting that can effectively be employed improve indoor air quality. Moreover, it confirmed trichloroethylene urban-ambient level also could enhance efficiency naphthalene when applying technology inside vehicles.
