污水中有机污染物的光催化降解研究

Study on Photocatalytic Degradation of Organic Pollutants in the Sewage

本文报道了一种利用枸杞子制备的金纳米颗粒来降解对硝基苯酚的研究。以枸杞子为还原剂,在水解条件下还原氯金酸制备金纳米颗粒,并且对其进行表征。采用硼氢化钠为还原剂,金纳米颗粒为催化剂,太阳光照下催化降解对硝基苯酚。结果表明15min后对硝基苯酚被还原成无污染的对氨基苯酚。

This paper reports on the use of Au nanoparticles(NPs) prepared by wolfberries to degrade 4-aminophenol. Using wolfberries as reductive agent, Au NPs are prepared by reducing chlorauric acid under hydrolysis conditions, and characterized. Using sodium borohydride as reductive agent and Au NPs as catalyzer, Catalyzing and degrading 4-nitrophenol, under sunlight incident conditions. The result shows that 4-aminophenol is reduced to pollution-free 4-aminophenol after 15 minutes.
