最新的《火电厂大气污染物排放标准》对烟气中SO2和汞的含量做出了严格的规定。该文利用连续光源并基于差分吸收光谱技术分别对单一组分SO2、气态单质汞Hg0及两者的混合气体进行了实验研究。研究表明：对于单一组分SO2的检测，利用傅里叶变换滤法比最小二乘法的反演精度更高；对气态单质汞Hg0的检测，利用特征波长处最大值法的反演精度从整体上稍高于峰面积法；对SO2及Hg0混合组分的检测，先由傅里叶变换反演SO2浓度，再利用浓度关系曲线反演Hg0。结果表明：对于混合气体SO2反演误差不超过5%，而SO2的存在将对Hg0造成更大的干扰，Hg0的反演误差超过20%。

There are strict rules for SO2 and mercury emissions from stationary sources in the latest emission standard of air pollutants for thermal power plants.. The paper mainly study on the concentration retrieval of the single SO2, single Hg0 and their gas mixture by using of continuum source. Studies have shown that for single SO2, Fourier transform filtering is better than the least squares method;For single Hg0, the maximum value at the characteristics wavelength is superior to the peak area method; For the gas mixture, after retrieving the concentration of SO2 with the Fourier transform filtering, then using the concentration relationship curves to retrieve the Hg0. The results show that, for gas mixture, the retrieval error of SO2 is less than 5%, however, the exist of SO2 will cause a greater interference to Hg0 , the retrieval error of Hg0 is more than 20%.
