摘要
PURPOSE: An europium(III) cation trapped potassium natrolite, a manufacturing method of the same, and a carbon dioxide storage containing the same are provided to use carbon dioxide as a storage and a separator by applying pressures and heat to nitrolite. CONSTITUTION: A manufacturing method of an europium(III) cation trapped potassium natrolite includes the following steps: a nitrolite mixed aqueous solution is obtained by mixing KNO_3 aqueous liquid and nitrolite; the nitrolite mixed solution is heated at a temperature between 20 and 90 Deg C for 12-48 hours to prepare potassium natrolite; an europium(III) nitrate aqueous solution is mixed with the potassium natrolite; and pressure of 1.5-4.5 GPa is applied to the mixture.
