Zeolite molecular sieves muaj kev sib cais muaj zog ntawm nitrogen thiab oxygen.Nws muaj cov qauv thiab cov yam ntxwv ntawm cov siv lead ua, qhov saum npoo yog lub cev pob txha, thiab cov kab noj hniav sab hauv tuaj yeem ua lub luag haujlwm ntawm adsorbing molecules.Muaj cov pores txuas rau ib leeg ntawm cov kab noj hniav, thiab cov molecules dhau los ntawm qhov pores.Vim qhov huv huv ntawm qhov hws, qhov pore loj faib ntawm molecular sieve yog sib xws.Molecular sieves xaiv adsorb molecules raws li qhov loj ntawm qhov pores hauv lawv cov muaju, uas yog, adsorb molecules ntawm qee qhov loj me thaum rov ua cov khoom loj dua.
