Emissions caused by polluting gases, such as carbon dioxide, are one of the main contributors to generation greenhouse effect that leads global warming, responsible for climate change. An alternative mitigating these emissions is use adsorbents capable capturing CO2. Zeolites considered most effective in gas adsorption and separation technologies due their high specific area pore size and, consequently, greater capacity when compared other commonly used materials. Despite this, reagents syntheses source silica often make obtaining materials more expensive. Seeking overcome this limitation, work, (for CO2 capture) were developed with a zeolitic structure using low-cost from beach sand called MPI synthesis process eco-friendly. The crystallization time was studied, an LTA zeolite period 1 h (ZAM h), relative crystallinity 74.26%. obtained characterized techniques X-ray diffraction (XRD), fluorescence (XRF), absorption spectroscopy infrared region Fourier transform (FTIR), scanning electron microscopy (SEM), thermal analysis. evaluation experimental isotherms showed Aerosil®200 (standard zeolite) MP had capacities 5.25 mmol/g 4.83 CO2, respectively. mathematical models indicated zeolites fit Temkin model best same trend, calculated 3.97 3.75 mmol/g,
