Dab tsi yog lub hauv paus ntsiab lus ntawm kev lim cov khoom nrog cov ntawv lim

Lub hauv paus ntsiab lus ntawm kev lim cov khoom nrog cov ntawv lim yog nyob ntawm qhov sib txawv ntawm cov khoom sib txawv thiab lawv cov kev sib cuam tshuam. Cov ntawv lim feem ntau yog tsim los ntawm cov ntaub ntawv fiber ntau lossis lwm cov ntaub ntawv ntxeem tau, nrog ntau qhov pores me me. Thaum cov khoom sib tov dhau los ntawm cov ntawv lim, cov khoom loj dua tsis tuaj yeem dhau los ntawm qhov pores, thaum cov khoom me me tuaj yeem ua tau.

Cov ntawv lim tuaj yeem lim tawm cov khoom loj dua lossis cov khoom raug tshem tawm, thaum tso cai rau cov khoom me me, molecules, lossis ions hla dhau. Qhov no yog vim hais tias cov khoom loj dua thiab tsis tuaj yeem dhau los ntawm qhov pores ntawm cov ntawv lim, thaum cov khoom yaj, cov molecules lossis ions me dua thiab tuaj yeem dhau ntawm qhov pores ntawm cov ntawv lim.

Tsis tas li ntawd, lub pore qauv ntawm cov ntawv lim tuaj yeem cuam tshuam nrog cov khoom siv. Piv txwv li, qee cov ntawv lim dej muaj cov teebmeem electrostatic los yog cov khoom siv tshuaj lom neeg, uas tuaj yeem adsorb lossis ntes tau them lossis tshuaj lom neeg cov tshuaj molecules. Qhov no ua rau cov ntawv lim dej kom zoo lim tawm cov khoom tshwj xeeb.

Hauv cov ntsiab lus, lim ntawv ua tiav pom los ntawm qhov pore loj ntawm cov khoom siv thiab kev sib cuam tshuam nrog cov khoom, yog li cais cov khoom loj dua lossis cov khib nyiab pov tseg thaum tso cov khoom me me dhau los.
