Kev ua haujlwm thiab kev siv cov yam ntxwv ntawm activated carbon

Ua ntej, daim ntawv thov ntawmactivated carbon

1, lub tsev tshiab: siv los nqus cov huab cua sab hauv tsev ntawm lub tsev tshiab thiab txuas ntxiv tso rau hauv cov huab cua kho kom zoo nkauj formaldehyde, volatile phenol, nitrogen dioxide thiab radon thiab lwm yam teeb meem, tshem tawm cov rooj tog kom sai.

2, rooj tog: siv los nqus cov rooj tog txuas ntxiv tso tawm cov khoom kho kom zoo nkauj formaldehyde, volatile phenol, thiab ntau yam tsw.

3, wardrobe, bookcase, khau txee: kom tshem tawm tsw, silt, noo noo, tiv thaiv kab, tsw, sterilization, cia, thiab lwm yam.

4, chav dej: deodorizing sterilization, roj tshiab.

5, ntoo hauv pem teb: kom tsw ntxhiab, noo noo, tsw ntxhiab, npauj pov thawj, txij nkawm thiab tu ntawm ntoo pem teb tsis deformed.

6, lub tsheb: nqus txhua yam khoom phom sij hauv lub tsheb tshiab thiab txhua yam ntxhiab tsw hauv lub tsheb qub.

7, computers, tsev khoom siv, adsorption, txo kev puas tsuaj ntawm cov tshuaj radioactive rau tib neeg.

8, tuam txhab chaw ua haujlwm, chav tsev so thiab lwm qhov chaw pej xeem: ntxuav cov pa hauv tsev, tshem tawm cov ntxhiab tsw.

Qhov thib ob, lub luag haujlwm thiab kev ua tau zoo ntawm cov pa roj carbon activated

Activated carbon tseem hu ua active carbon dub. Nws yog amorphous carbon nyob rau hauv daim ntawv ntawm dub grey hmoov los yog cov khoom me me. Cia peb saib lub luag haujlwm ntawm cov pa roj carbon activated. Cov pa roj carbon activated muaj qhov tseem ceeb "lub cev adsorption" thiab "kev tshuaj ntsuam xyuas tshuaj adsorption", uas tuaj yeem adsorb qee cov tshuaj analytical compounds kom ntseeg tau tias tshem tawm cov txiaj ntsig xav tau. Cov pa roj carbon activated tam sim no tau siv dav los ntxuav huab cua hauv tsheb thiab tsev. Cov pa roj carbon activated yog ib yam ntawm cov khoom ntxeem tau cov ntsiab lus carbon cov khoom, nws txoj kev vam meej void qauv ua rau nws muaj thaj tsam loj heev, yog li nws yooj yim rau kov cov khoom tsis zoo hauv huab cua, qhov muaj zog adsorption quab yuam nyob ze ntawm lub tshuab ua pa carbon qhov. tam sim ntawd nqus cov tshuaj phem molecular mis rau hauv lub qhov, yog li cov pa roj carbon activated muaj zog adsorption muaj peev xwm.

Thib peb, cov yam ntxwv thiab txheej txheem ntawm activated carbon adsorption

Qhov zoo ntawm cov pa roj carbon activated adsorption yog qhov xim tus nqi nrawm dua, kev ua haujlwm adsorption nyuaj, thiab cov xim hauv cov potion tuaj yeem ua tau zoo adsorbed, thiab cov sediment ntawm potion tuaj yeem txo qis, tsis cuam tshuam rau qhov concentration ntawm lwm yam khoom. ntawm potion thiab tshuaj.

Thaum yuav khoom, thov nco ntsoov tias qhov me me ntawm cov khoom, cov nyhuv zoo dua. Vim tias qhov loj dua nws qhov chaw tag nrho, qhov pores ntau dua nws muaj. Txawm li cas los xij, cov khoom yuav tsum tsis txhob ua kom zoo rau hauv cov hmoov, kom tsis txhob ua rau tsis yooj yim rau kev siv thiab cuam tshuam rau kev lim dej ntawm lub lim. Feem ntau, qhov loj me ntawm li 1MM hauv txoj kab uas hla yog qhov zoo dua.

Lub cev adsorption, tseem hu ua van der Waals adsorption, yog tshwm sim los ntawm lub zog electrostatic los yog van der Waals attraction ntawm cov adsorbent thiab cov adsorbent molecules. Thaum lub molecular attraction ntawm cov khoom thiab cov roj ntau dua qhov attraction ntawm cov roj molecules, cov pa roj molecules yuav condense rau ntawm cov khoom nto txawm tias lub siab ntawm cov roj yog qis dua qhov kev khiav hauj lwm kub thiab saturation vapor siab.
