【 摘 要 】

Attapulgite catalyst supported on titanium dioxide formed titanium dioxide supported silver Phosphotungsten vanadate composite catalyst, which can effectively degrade pharmaceutical wastewater solution by visible light. In this experiment, the optimum conditions for the degradation of pharmaceutical wastewater were as follows: 100 mL pharmaceutical wastewater was used in the photodegradation reactor, pH was adjusted to 5, 0.5 g/L attapulgite catalyst was added, and at room temperature, pharmaceutical wastewater was irradiated by high-pressure mercury lamp illumination. The degradation rate reached 80% after 30 minutes of reaction.
