UV Activated Persulfate Technique for 1,1,1-Trichloroethane Degradation in Aqueous Solution

  • 摘要: 分别采用不同的紫外光源(UV、VUV)活化Na2S2O8处理水溶液中的TCA(1,1,1-三氯乙烷),考察溶液初始pH、阴离子及HA(腐殖酸)对TCA降解过程的影响. 结果表明:UV/Na2S2O8体系和VUV/Na2S2O8体系中,TCA可分别在60和30 min内完全去除,氧化降解过程符合准一级反应动力学方程,反应动力学常数分别为0.06和0.14 min-1;溶液初始pH越高越不利于TCA的降解;Cl-和HCO3-的存在能够抑制TCA降解,HCO3-的抑制效果较Cl-更为显著;ρ(HA)大于10 mg/L时能明显降低TCA的去除率. 2种体系均能使TCA基本脱氯,不产生二次污染.
