Test Method
1)Supplied material:Tiles coated with TiO2 photocatalysis
2)Odorous substance:Ammonia NH3,Trimethylamine (CH3)3N,Hydrogen sulfide H2S
3)Measurement method:Infused odorous substances with an initial concentration of 30ppm into four "five liter"containers in which the photocatalyst tiles wereinstalled.Two fluorescent lamps placed 150 cm from the tiles.Theresidual concentration was measured after ten minutes,halfhour,one,two and five hours using the gas detector tube "Kitagawa model".
