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 cov pob txha 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 cov pores.Vim qhov huv ntawm qhov hws, qhov pore loj faib ntawm cov molecular sieve yog heev uniform.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 ntawm cov khoom loj.
