| 摘 要： | 以Bi（NO3）3·5H2O和NaVO3·2H2O为原料，采用水热法合成了BiVO4粉末，并对其进行了XRD表征。以模拟含酚废水为目标降解物，以催化剂的用量、氧化剂用量、光源、光照时间为考察对象，研究了BiVO4催化剂的光催化性能。结果表明，在模拟含酚废水用量为30mL时，BiVO4加入量为0．03g，H2O2用量为5．4mL，光照时间为1h，光源为500W汞灯的条件下，对模拟含酚废水的降解率可达到98％以上。

| Abstract: | A visible light driven catalysis BiVO4 is prepared by hydrothermal synthesis, and is characterized lay XRD. Taking the simulated phenol - containing wastewater as the research material, the degradation activity of Bi- VO4 is tested by the research objects of the amount of catalysis, the concentration of oxidant, the light source and the light time. The results show that, the degradation rate of BiVO4 to simulated phenol - containing wastewater can reach 98% under the optimal conditions, which is 0.03 g of catalysis,5.4mL of H202, lh of light time, 500W of mercury Lamp light. |
