Abstract

Absorbing carbon dioxide by porous solid material is one of the most effective methods aiming to treat, cut down carbon dioxide emission, solving climate change that is occurring globally. The paper presents the result of manufacturing carbon dioxide-absorbing particles based on calcium hydroxide as main material and other components (silica, calcium oxide, lithium chloride, ethyl violet indicator, etc.). Manufactured material has specific surface area of 15.597 m²/g, pH of the extract is 11.98, CO₂ absorbing capacity reaches 160 liters/kg, has ability of changing color from white to dark violet when the particles are saturated with CO₂.
