| 中文摘要 |
| 对Mn2+催化臭氧（O3）液相氧化脱除二氧化硫（SO2）进行了实验研究，以揭示Mn2+对臭氧液相氧化SO2的影响.采用标准碘量法测定了O3浓度曲线.实验比较了添加Mn2+前后吸收液对SO2的脱除效率，并研究了O3与SO2摩尔比（［O3］/［SO2］）、Mn2+浓度对SO2脱除效率的影响.在［O3］/［SO2］=0.5、未添加Mn2+时O3对SO2的氧化效率为35%，而添加Mn2+后的氧化效率达到70%.随着［O3］/［SO2］的增大，SO2脱除效率逐渐增加，而且脱除效率也随Mn2+浓度的增加而增加，合适的Mn2+浓度范围为1.2×10-2～1.2×10-1 mol/Ｌ. |
| 英文摘要 |
| The removal of SO2 by Mn2+ catalytic aqueous ozonation was investigated by experiment, so as to find the effects of Mn2+ for aqueous removal of SO2 by ozonation. The concentration curve of ozone was drawn by standard iodine method. The operating factors included mole ratio of ozone to sulfur dioxide and concentration of Mn2+.When absorption solution has no Mn2+ ,the removal efficiency ofSO2 was 35% at ［O3］/［SO2］=0.5,but the efficiency was 70% when Mn2+ was put into absorption solution at the same value of ［O3］/［SO2］.With the increasing of ［O3］/［SO2］,the removal efficiency of SO2 increases. And as concentration of Mn2+ increases, the efficiency also increases. There is an appropriate concentration range which is 1.2×10-2-1.2×10-1 mol/Ｌ for Mn2+. |
