摘要
水溶液中1,2-二氯苯、1,3-二氯苯和1,2,4-三氯苯在薄层TiO_2催化作用下发生光致分解(氙灯光源,波长大于300nm,辐射通量600mW·cm^(-2))。薄层TiO_2的光催化活性与玻璃表面薄层TiO_2的附着量有关,实验表明,其最佳TiO_2附着量约为5.8×10^(-2)mg·cm^(-2)。
The photodecomposition of 1, 2-and 1, 3-dichlorbenzene, and 1, 2, 4-trichlorbenzene in water occurred under the irradiation of Xenon lamp (λ>300nm, I_e=600mW·cm^(-2)) and the catalysis of TiO_2 film.The photoactivity of TiO_2 film was related to the surface adhesive amount of TiO_2 on the glass. It was cxperimently showed that the optinum adhesive amount of TiO_2 was about 5.8×10^(-2)mg·cm^(-2)
