PURPOSE: To purify waste matter economically and easily by using a photocatalyst activated in accordance with light energy in a method for removing harmful substances contained in the waste matter. n CONSTITUTION: The waste samples introduced from a sample inlet 51 are introduced to a reactor 31 via a circulator 52. The reactor consists of light permeable material and a photocatalyst 41 is set at the bottom part. A semiconductor such as TiO 2 and ZnO and a molecular photocatalyst such as porphyrin are used as the photocatalyst. The waste introduced in the reactor is photodecomposed with the light which is emitted from a light source 61 and introduced through a lens 71 and removed and the purified substances are discharged from a sample outlet 53. n COPYRIGHT: (C)1985,JPO&Japio |
