Dynamic online monitoring of chemical reaction process is of significant importance to the research of interdisciplines including chemistry, bioscience and environmental science etc, which also is a research frontier of analytical chemistry. This project will focus on the development of a Cycliing Dynamic Online Analytical System (CDOAS) that is based on the periodical occurrence of the rapid chemical reaction. The CDOAS can be combined with rapid spectral detection techniques such as UV-visible spectroscopy, fluorescence spectrum, chemiluminiscence, infrared spectroscopy and Raman spectroscopy etc., to develop dynamic online analytical techniques for real-time monitoring signals produced by different chemical reaction processes, which can be used for the monitoring of chemical reaction processes and the study of the chemical reaction mechanism. The advantages of DOAS including: It realizes automated control of the periodical occurrence of the rapid chemical reactions and the dynamic monitoring of the signal.It can be easily combined with spectral detection techniques.It can offer more multidimensional information relating to the chemical reaction process. The real-time and online monitoring chemical reaction process in favor of the study of the chemical reaction mechanism.It is a green technology due to the chemical reactions can occur complete in the system. The research results will promote the fundamental research of chemistry, bioscience and environmental science etc., and will provide a fast, efficient, accurate, reliable and environment-friendly new online analytical instruments and analytical methods for analysis and quality inspection.
