Thaum lub sijhawm adsorption, ib txwm muaj decrease nyob rau hauv seem quab yuam ntawm qhov chaw, piv txwv li, muaj qhov txo qis hauv lub zog saum npoo uas tshwm sim thaum tshav kub. Adsorption, yog li ntawd, invariably ib txheej txheem exothermic.
Yuav ua li cas rau saum lub zog thaum lub sij hawm adsorption?
Thaum lub sijhawm adsorption ntawm cov pa roj rau ntawm cov khoom muaj txo qis hauv lub zog saum npoo, piv txwv li, nws yog txheej txheem exothermic. … Ib zaug ntxiv thaum cov pa roj adsorbed, txoj kev ywj pheej ntawm kev txav ntawm nws cov molecules yuav raug txwv. Qhov no ua rau txo qis hauv entropy ntawm cov pa tom qab adsorption.
Puas adsorption nce nrog thaj chaw saum npoo?
Xwm ntawm Adsorbent:
Vim tias adsorption yog qhov tshwm sim saum npoo, adsorption nce nrog nce nyob rau thaj tsam ntawm cov adsorbent.
Thaum thaj tsam ntawm qhov adsorbent nce qhov adsorption?
14.8.
qhov zoo tshaj plaws adsorbent ntau npaum yog qhov tseem ceeb, uas cuam tshuam rau tus nqi ntawm adsorbed adsorbate. Qhov chaw saum npoo nce ntxiv nrog kev nce qib adsorbent. Txhawm rau kom tsis txhob noj ntau dhau ntawm adsorbent, qhov kev nrhiav kom pom qhov zoo yog qhov tsim nyog.
Yuav ua li cas thaum lub sij hawm adsorption?
Adsorption yog qhov adhesion ntawm atoms, ions lossis molecules los ntawm cov pa roj, kua lossis yaj cov khoom rau saum npoo. Cov txheej txheem no tsim ib zaj duab xis ntawm cov adsorbate rau saum npoo ntawm cov adsorbent. Cov txheej txheem noSib txawv ntawm kev nqus, uas cov kua dej (lub absorbate) yog yaj los ntawm los yog permeates ib tug kua los yog khoom (lub absorbent).
