| 摘 要： | 研究了以悬浮态TiO2为催化剂,在H2O2存在的条件下,对壬基酚聚氧乙烯醚的光催化降解反应。分别考察了pH值、TiO2和H2O2的加入量、壬基酚聚氧乙烯醚的初始浓度以及光照时间对降解反应的影响。结果表明:在pH值为5,H2O2质量浓度为30mg/L的条件下,对初始质量浓度为50mg/L的壬基酚聚氧乙烯醚溶液光照4h后降解率达46.32%。

| Abstract: | With the existence of H2O2, a photocatalytic degradation reaction on nonylphenol ethoxylates with suspended TiO2 as a catalyst was studied. The effects of the pH values, the dosage of TiO2 and H2O2, the initial concentration of nonylphenol ethoxylates and the illumination time on the degradation reaction were studied respectively. The results show that: when pH value is 5, the mass concentration of H2O2 is 30 mg/L, after 4 hours of illumination, the degradation rate of nonylphenol ethoxylates which initial concentration is 50 mg/L reaches 46.32%. |
