Yog tias cov roj tsub zuj zuj ntawm cov khoom siv los ntawm qhov tsis muaj zog van der waal rog ces nws yog hu ua physisorption lossis lub cev adsorption. Ntawm no hauv physisorption tus nqi ntawm adsorption txo qis nrog qhov nce ntawm qhov kub thiab nce nrog nce siab. Nws yog txheej txheem thim rov qab.
hom adsorption twg yog thim rov qab?
5.9.
Zarrouk (2008) tau qhia tias muaj peev xwm muaj tshuaj lom neeg adsorption (chemisorption) uas tuaj yeem hloov tsis tau thiab lub cev adsorption (physisorption) uas yog thim rov qab.
Puas yog lub cev adsorption thim rov qab?
Adsorption yog qhov tshwm sim saum npoo. … Nyob rau hauv cov ntaub ntawv ntawm cov roj theem, roj yog condensed los ntawm lub capillarity thiab hloov mus rau cov kua, uas ua rau kom cov adsorption. Ua ke, cov no yog hu ua lub cev adsorption. Lub adsorption yog nrawm thiab thim rov qab, uas txhais tau tias nws tuaj yeem yooj yim desorbed los ntawm cua sov lossis decompression.
Yuav ua li cas nqus tau rov qab los ntawm qhov xwm txheej?
Lub cev adsorption yog thim rov qab rau hauv qhov xwm txheej (vim muaj lub zog van der waals tsis muaj zog) thiab cov tshuaj adsorption yog irreversible nyob rau hauv cov xwm (vim muaj cov tshuaj muaj zog bonds).
Puas yog tshuaj adsorption thim rov qab?
Tshuaj adsorption, tseem hu ua chemisorption, ntawm cov khoom siv yog ua tiav los ntawm kev sib koom ntau ntawm cov hluav taws xob nruab nrab ntawm qhov chaw ntawm adsorbent thiab adsorbate los tsim kom muaj covalent lossis ionic daim ntawv cog lus. Yog li,tshuaj adsorption tej zaum yuav tsis tau tag nrho reversible, thiab tuaj yeem xav tau lub zog siab rau kev tsim dua tshiab.
