Above-mentioned processing method 1~8 is implemented to space in the drier of the acetic acid comprising 3.77~9.00ppm or so respectively, Carry out the evaluation of deodorizing effect.The result being shown in Table 1.(the test example in the case of by ozone supply to object space 2), acetic acid is almost without being decomposed, on the contrary, in the case that the mist of the dispersion liquid of photocatalyst particles is supplied to object space In the case of the mist and ozone of the dispersion liquid of (test example 3,5,7) and supply photocatalyst particles (test example 4,6,8), acetic acid Almost it is decomposed.In addition, though distilled water is supplied to the situation of object space (test example 1), it has been found that acetic acid Concentration reduces, but it is thought that because being present in the acetic acid in object space with gaseous state, a part is dissolved in processing institute In the water used, reduced so as to cause the air concentration of acetic acid.
Thus it shows:(1) carboxylic acid is difficult to decompose in the processing that ozone is used alone;(2) photocatalyst particles are being used Processing in, no matter have ozone free that can efficiently decompose carboxylic acid.
[table 1]
[embodiment 2]
Above-mentioned processing method 1~8 is implemented to space in the drier of the benzene comprising 2.50~3.67ppm or so respectively, into The evaluation of row deodorizing effect.The result being shown in Table 2.Distilled water (test example 9) or ozone (test example 10) are supplied To object space, benzene is almost without being decomposed.In addition, the mist of TiO 2 particles dispersion liquid is supplied to object sky Between in the case of (test example 11) or supply TiO 2 particles dispersion liquid mist and ozone in the case of (test example 12), nothing Method assert that benzene decomposes.On the other hand, although in the case where supplying tungstic acid particle dispersion to object space (test example 13) benzene is almost without being decomposed, but will be in the case of the mist of tungstic acid particle dispersion and ozone supply to object space (test example 14), about 57% benzene are decomposed.In addition, it is supplied by the mist of tungsten dioxide particle dispersion to object space In the case of (test example 15), about 28% benzene is decomposed, by the mist of tungsten dioxide particle dispersion and ozone supply to object In the case of space (test example 16), about 67% benzene is decomposed.
Thus it shows:(1) in the processing that ozone is used alone, aromatic compound is difficult to decompose;(2) dioxy is being used In the processing for changing titanium particle, there is ozone free aromatic compound to be all difficult to decompose;(3) although tungstic acid is used alone It is difficult to decompose aromatic compound, but in the state of coexisting with ozone in the case of particle, aromatic compound can be decomposed; (4) although tungsten dioxide particle individually can also decompose aromatic compound, in the state of being coexisted with ozone, Neng Gougeng Efficiently decompose aromatic compound.
