Shimadzu Review 79[1・2] (2022)


Reducing carbon dioxide (CO2) emissions and other greenhouse gases has become a global challenge with a carbon neutral society as the eventual goal. In pursuit of this goal, research and development is underway into CO2-fixing technology and techniques for converting fixed CO2 into useful products.
A variety of approaches can be taken to CO2 fixation, including chemical, physical, and biological, and evaluating these techniques requires means of quantitating the fixed CO2 and monitoring CO2-fixing processes. This article looks at chemical absorption, physical adsorption, membrane separation, and biological methods of CO2 fixation and presents a case study in which the Shimadzu TOC-L total organic carbon analyzer and Shimadzu CGT-7100 transportable gas analyzer were used to evaluate actual CO2-fixing technology.
