Oxone/紫外氧化降解水中有机磷农药氧乐果的研究

摘要

选择了氧乐果废水的处理工艺,重点探究了Oxone/紫外氧化降解氧乐果的影响因素.结果表明,Oxone/紫外氧化工艺氧化降解氧乐果优于自然光照、紫外光照、Oxone氧化等工艺.氧乐果初始质量浓度为10 mg/L、pH=2.03、反应温度为35 ℃、10 mmol/L Oxone试剂用量为1.0 mL时,降解20 min的氧乐果降解率可达99.8%.%Omethoate degradation process was selected.Factors of Oxone/UV in aqueous solutions were studied. Results showed Oxone/UV was better than natural lighting,UV lignting and Oxone.The degradation efficiency of omethoate could reach 99.8% at 20 min under condition of omethoate initial mass concentration 10 mg/L,pH 2.03,reaction temperature 35 ℃ and Oxone(10 mmol/L)dosage 1.0 mL when Oxone/UV was selected.
