Perovskite-type complex oxides La0.9 Ce0.1 MnO3 were prepared by glycine-mthod, the structure and property of the samples were characterized by X-ray diffraction(XRD) and scanning electron microscopy(SEM). The photodegradation of simulated phenol containing wastewater by La0.9 Ce0.1 MnO3 was conducted with resorcinol as pollutant source and UV lamp as light source, the effect of reaction time, solution pH and catalysts dosage on the degradation rate was investigated. Results showed that the degradation rate of resorcinol was increased with increasing the reaction time, then the degradation rate access a fixed value; the strong acid and strong alkali would inhibit the photo-degradation of resorcinol, the optimal pH condition was 6. 5. Increasing the catalysts dosage could enhance the resorcinol degradation, while when the catalyst dosage was more than 0. 20 mg/mL, the enhancement was negligible.%采用氨基乙酸法制备催化剂钙钛矿锰氧化物(La0.9Ce0.1MnO3),用X射线衍射(XRD)技术对所制备的催化剂进行表征.采用模拟含酚废水,以间苯二酚为污染物、紫外灯为光源,考察反应时间、溶液pH以及催化剂加入量对催化剂降解间苯二酚的影响.结果表明,随着反应时间的延长,间苯二酚的降解率逐步增大,最后趋于平稳；溶液最佳pH在6.5左右,强酸和强碱条件均不利于间苯二酚的降解；随着催化剂加入量的增大,间苯二酚的降解率也随之增大,但是当催化剂加入量达到0.20 mg/mL时,再提高催化剂加入量,对间苯二酚的降解率没有明显的影响.
