Investigation of Hydrogen Sulfide Degradation Using Electrodeless Iodine-UV Lamp

  • 摘要: 采用微波激发方式使无极碘灯发生放电,产生207 nm紫外辐射,并用于降解H2S气体.考察了初始ρ(H2S)、停留时间和微波电源功率等因素对H2S降解的影响.结果表明:H2S在微波无极碘灯停留时间为1.75 s时,其降解率随初始ρ(H2S)的升高而降低.初始ρ(H2S)为57.5 mg/m3时,H2S降解率为20.5%;初始ρ(H2S)为7.3 mg/m3时,H2S降解率可达到64.2%.在保持初始ρ(H2S)及停留时间不变的情况下,H2S降解率随电源功率的增加而提高.H2S经微波碘灯光解后的最终产物含有SO42-.
