Vim li cas cov pa roj carbon activated tuaj yeem nqus cov pa lom tab sis tsis yog oxygen?

1, Feem ntau hais lus, muaj ob hom adsorption: ib qho yog lub cev adsorption, uas yog los ntawm van der Waals quab yuam ntawm molecules, uas yog lub unbalanced electron huab nyob rau hauv txheej txheej ntawm lub molecule, uas ua rau lub molecule yuav adsorbed nrog. polarity; lwm yam yog tshuaj adsorption. , uas yog cov tshuaj tiv thaiv ntawm cov tshuaj adsorbed thiab cov khoom adsorbed los tsim lwm yam khoom.

2,Lub cev adsorption feem ntau tuaj yeem desorbed (txo) los ntawm cov cua sov yooj yim lossis lwm yam kev kho mob, thiab cov tshuaj adsorption yog qhov nyuaj dua vim muaj kev sib koom ua ke.

3,Feem ntau ntawm activated carbon adsorption belongs rau lub cev adsorption. Suav pores zoo ib yam li molecular sieves yog tsim nyob rau hauv lub activated carbon. Vim tias sab hauv ntawm lub qhov hws yog qhov chaw uas cov hluav taws xob zoo li qub tsis sib npaug, cov nyhuv ntawm cov pa roj carbon activated ua rau cov hluav taws xob zoo li qub tsis sib npaug, yog li nws muaj zog adsorption. Nws tuaj yeem pom tias cov hmoov av adhesion ntawm phab ntsa thiab lub ces kaum ntawm lub tsev zoo sib xws. Lub ces kaum yog qhov chaw uas hluav taws xob zoo li qub tsis sib npaug, thiab nws yooj yim nqus plua plav). Txawm hais tias macromolecules xws li chlorine Cl2 (ntawm no, macromolecules xa mus rau cov huab hluav taws xob loj), cov huab cua sab nrauv tuaj yeem cuam tshuam, ua rau electrostatic tsis txaus thiab adsorption.

4,Feem ntau ntawm cov pa phem yog cov sib txuas (tshwj tsis yog cov tshuaj chlorine), thiab lawv cov hluav taws xob zoo li qub tsis sib npaug, yog li lawv tau yooj yim adsorbed los ntawm cov pa roj carbon activated. Gases xws li oxygen thiab nitrogen yog statically balanced, thiab cov molecules tsis loj (lub nucleus yog qhwv nyob rau hauv nws tus kheej electron huab. ", yog li cov adsorption yog nyuaj.
