Dynamical Study of Reactive Absorption of Gaseous Species

Mass transfer process is one of the very important elementary rate processes relevant to reactiveabsorption in chemical reaction engineering and also the uptake of gaseous trace species from theatmosphere to aerosol surfaces. This research aimed at the measurements of uptake coefficients usingthe novel impinging flow methodthe understanding of the process based on the liquid phase chemical反应and also tile development of the technology for direct measurement the surface species using laserspectroscopic and/or mass-spectroscopic methods.2. Uptake coefficients of halogen species，which are important atmospheric trace species in atmospheric chemistrywere measured using the impinging flow method. In particularthe uptake coefficient of I D22 D2 was measured under various conditions，并分析了新定义的numerical simulation方法的方法。to be controlled by liquid phase chemical reactions.3. Technology for direct measurement of surfacespecies was developed. They were multiphoton ionization method of surface species on liquid phasesurfaces,surface desorption mass-spectrometry for species on solid surfaces such as ice prepared at lowtemperature.这些新技术无法completely established， however，the potentiality of他们清楚地解释了。

Uptake coefficients of halogen species, which are important atmospheric trace species in atmospheric chemistry, were measured using the impinging flow method. In particular, the uptake coefficient of IィイD22ィエD2 was measured under various conditions, and analyzed by means of the newly devised numerical simulation method. The uptake process was found to be controlled by liquid phase chemical reactions.3. Technology for direct measurement of surface species was developed. They were multiphoton ionization method of surface species on liquid phase surfaces, and surface desorption mass-spectrometry for species on solid surfaces such as ice prepared at low temperature. These new technology could not be completely established, however, the potentiality of them was clearly demonstrated.
