| 摘 要： | 研究了光源波长、光照强度以及阿维菌素初始浓度对其光降解的影响,并系统考察了紫外吸收剂阿凡达、抗氧化剂BHT、光屏蔽剂纳米SiO_2和表面活性剂十二烷基硫酸钠对阿维菌素光降解的影响。结果表明:光源波长越短,光照强度越大,初始浓度越低,则阿维菌素的光解速率越高。紫外吸收剂、抗氧化剂及光屏蔽剂对阿维菌素光降解有显著抑制作用。

| Abstract: | The photodegradation effects of light source wavelength,light intensity,initial concentration were studied in this paper.Then,the photodegradation functions of ultraviolet absorbent,antioxidant BHT,light screener SiO2,surfactant sodium dodecyl sulfate (SDS) under different reaction conditions were analyzed.The results showed that the photolysis rate increased with the decrease of light source wavelength and initial concentration of abamectin.And there was a positive correlation between the light intensity and photocatalytic degradation rate.Ultraviolet absorbent,antioxidant,light screener,surfactant had obvious inhibition function on photocatalytic degradation. |
