This paper presents a laboratory study of the efficiency of absorbents and their ability to bind carbon dioxide. The absorbents tested were calcium hydroxide Ca(OH)2 and sodium hydroxide NaOH. The binding ability of each absorbent individually was tested, as well as their mixture in certain proportions and at different percentages of solution. The results showed that the chemical binding of carbon dioxide to the absorbents occurred in a very short time. The mixture of these two absorbents showed the highest efficiency. The absorbed carbon dioxide creates carbonates that can be precipitated and dried. This study represents a starting point for further studies, both laboratory and industrial, with the aim of reducing carbon dioxide emissions by using natural, cheap and easily available absorbents that have high absorption efficiency.
