Abstract
- Hydrogen sulfide, ammonia, formaldehyde, toluene, n-pentane and acetone were used as indoor gas pollutants. Using ozone synergistic photocatalysis technology, Ti02 was selected as photocatalyst and doped with Fe3+, and the effects of TiO2 modification and different gas flow rate, initial reactant concentration, relative humidity and ozone concentration on purification efficiency were investigated. The results show that when the gas flow rate in the reaction section is 1 m/s,the amount of ozone is 49.08 mg/m³, the relative humidity is less than 50%, and the system runs for 30 min, the average purification efficiency of 03/Fe-Ti02/UV technology for six kinds of gas pollutants is 65%.
