| 中文摘要: |
| 采用共溶胶凝胶法制备锰酸钇（YMnO3）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Na2S2O8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、Na2S2O8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，YMnO3催化剂用量为0.014 g、Na2S2O8浓度为160 mg/L，超声功率为200 W时，脱色降解的效果最佳。 |
| 英文摘要: |
| 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, Na2S2O8 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 YMnO3 catalyst, 160 mg/L Na2S2O8 and 200 W ultrasonic power. |
