| 摘 要： | 紫外吸收光谱法是利用不同气体在紫外波段对光具有选择吸收的特性来测量排放烟气中的气体成分和浓度。基于这种方法设计出一套能够实时、在线监测硫化氢的实验装置。在常温常压状态下,通过对测量的一次光谱进行分析,计算出硫化氢的标准吸收截面,选择合适的数据处理方法,减小浓度计算时的误差,可得出硫化氢的实时浓度值。

| Abstract: | UV absorption spectrometry is a method for measuring the gas component and its concentration by the characteristic of selective absorption for light in the UV-VIS region. Based on this method a set of new experimental devices for on-line monitoring of hydrogen sulfide is designed. At normal pressure and temperature,a standard absorption cross-section can be calculated through analyzing one absorption spectrum,selecting suitable data processing methods,thus obtaining the real-time concentrations of hydrogen ... |
