| 摘 要： | 将稳定同位素方法应用于闽南地区SO2在潮湿气溶胶表面氧化动力学研究中,在对大气中SO2的稳定硫同位素及大气气溶胶中可溶性硫的硫稳定同位素丰度的测定的基础上,用硫稳定同位素动力学方程计算SO2在潮湿气溶胶表面氧化速率与均相氧化速率比?结果表明:漳州地区潮湿气溶胶表面SO2非均相和均相氧化速率之比:K非/K均为1.13,厦门地区SO2非均相和均相氧化速率之比:K非/K均为0.36,这种差异主要是由相对湿度不同引起的。

| Abstract: | The stable isotope method was applied in the research about SO 2 heterogeneous oxidation reaction on deliquescent aerosol surface in Minnan area. By determining the abundance of stable sulfur isotope of SO 2 in the air and of soluble sulfur in the aerosol, the stable sulfur isotope reaction equation was used to calculate the ratio of homogeneous rate and heterogeneous rate of SO 2 on deliquescent aerosol surface. The results show that the ratio of homogeneous rate and heterogeneous rate of SO 2 on deliquescent aerosol surface is 1.13 in Zhangzhou area and 0.36 in Xiamen area, and the difference is caused by different relative humidity. |
