摘　　要：采用共溶胶凝胶法制备锰酸钇(YMnO_(3))催化剂,用扫描电镜(SEM)、X射线衍射(XRD)和红外光谱(FTIR)对催化剂进行表征。研究Na_(2)S_(2)O_(8)协同锰酸钇催化超声波降解日落黄,探究了pH、初始浓度、催化剂用量、Na_(2)S_(2)O_(8)浓度、超声功率对降解的影响。结果表明,在超声波条件下pH为3,日落黄初始浓度为50 mg/L,YMnO_(3)催化剂用量为0.014 g、Na_(2)S_(2)O_(8)浓度为160 mg/L,超声功率为200W时,脱色降解的效果最佳。The yttrium manganite catalyst was prepared by sol-gel method,and the catalyst was characterized by scanning electron microscopy(SEM),X-ray diffraction(XRD)and fourier transform infrared(FTIR).The ultrasonic degradation of sunset yellow catalyzed by yttrium manganite with sodium persulfate was studied.The effects of pH,initial concentration,catalyst dosage,Na_(2)S_(2)O_(8) concentration and ultrasonic power on degradation were investigated.The results showed that the optimum degradation conditions were pH 3,50 mg/L initial concentration of sunset yellow,0.014 g YMnO_(3) catalyst,160 mg/L Na_(2)S_(2)O_(8) and 200 W ultrasonic power.
