- 摘要：环境微界面过程是污染物在各环境要素中迁移转化的基本过程,也是研究污染控制方法的基础.发展原位和在线研究方法,对于揭示污染物在环境微界面的迁移转化规律和进行污染控制过程的研究具有重要意义.本文基于环境微界面过程的基本特征,在针对多相环境催化的原位研究方法基础上,分析了用于环境微界面过程的原位和在线研究方法所面临的挑战和相应对策,主要介绍了红外光谱、拉曼光谱和质谱等技术在气固环境微界面过程原位研究中的应用,提出了发展环境微界面过程原位和在线研究方法体系的构想.
- Abstract：Micro-interface processes are the primary processes for the transportation and transformation of pollutants in environment,and are also the basis for developing environmental pollution control technologies.It is important to develop in situ and online research techniques for the exploration of the transfer and transformation of pollutants on micro-interface.On the basis of the characteristics of micro-interface processes in environment and the in situ research methods applied in environmental heterogeneous catalysis,the challenge and countermeasure during the study of micro-interface processes were discussed.The application of infrared,Raman and mass spectroscopies in micro-interface processes study between solid and gas phase were also discussed in this article.Finally,the framework of in situ and online research methodology for micro-interface processes in environment was proposed.
