A carbon dioxide absorber is a device or material designed to capture and remove carbon dioxide (CO2) from the air or other gases. These absorbers are often used in various applications, including industrial processes, air purification systems, and environmental management. By reducing the concentration of CO2, they help mitigate the effects of climate change and improve air quality. Common materials used in carbon dioxide absorbers include amines, zeolites, and activated carbon. These substances work by chemically binding with CO2 or physically trapping it, allowing for its removal from the environment. The captured carbon dioxide can sometimes be reused or stored safely, contributing to sustainability efforts.
