This study aims to absorb the carbon monoxide (CO) gas using Lampung natural zeolite as an adsorbent. Natural Zeolite has porous crystal structure, large surface area, high thermal stability, non-toxic, and effective. Natural zeolites contain many impurities, then it must be activated. Activation of natural zeolite was done by soaking in a solution of 2% HF for 10 minutes with stirring. Furthermore, dealumination natural zeolite carried out  by soaking in a solution of 6 M HCl for 30 minutes. Zeolite was soaked with a solution of 0.1 M NH4Cl and then was calcined.  Then Activated Natural zeolite was tested the adsorption of cabon monoxide gas from burning tissue paper. Variations in particle size of the zeolite is 53-106 μm, 106-150 μm and 150-212 μm. The results showed that activated natural zeolite with a particle size of 53-106 microns can adsorb CO gas at 379 ppm (12.2%) of the initial concentration for 20 minutes.
