Reducing the Concentration of Carbon Dioxide in Indoor Air Using Absorption-Based Capture

Preservation of the quality of the environment and the safety of human life depend on a multitude of factors.Recently, one of the most significant of these factors has been increasing carbon dioxide content in the Earth's atmosphere and the air in industrial facilities and residential and public buildings.Capturing CO2 to lower its content in the air is among the most topical issues in current scientific studies.The presented study demonstrates the adverse effects of CO2 on human health and climate change.The authors conduct a patent search and an analysis of literary sources on methods of CO2 removal and systematize and substantiate the expediency of further experimental studies on improving sorption-based removal.The study presents a specially developed toolkit, including an experimental setup for testing various substances and reagent solutions for efficiency of CO2 capturing in indoor spaces, a program methodology of respective experiments, and a dedicated software program "Processing of the results of experimental studies of the properties of CO2 absorbers".The research findings indicate that all the examined solutions can be used to reduce CO2 concentration in the air in indoor spaces, although the most efficient of these is a solution of caustic soda.The obtained results are of undoubted interest for the development of technologies and methods of capturing CO2 to reduce its concentration in the air in residential, public, and industrial buildings, in emergency shelters, and in the atmosphere.
