Koj paub dab tsi rau activated carbon?

Yuav ua li cas yog activated carbon?

Cov pa roj carbon activated yog cov khoom siv ntuj tsim uas muaj cov ntsiab lus carbon siab.Piv txwv li, thee, ntoo lossis txiv maj phaub yog cov khoom siv zoo meej rau qhov no.Cov khoom tsim tau muaj qhov porosity siab thiab tuaj yeem nqus cov pa phem ntawm cov pa phem thiab ntxiab lawv, yog li ua kom huv huv huab cua, roj thiab kua.

Cov ntawv twg tuaj yeem ua kom cov pa roj carbon monoxide nkag rau hauv?

Cov pa roj carbon activated tuaj yeem tsim ua lag luam hauv cov ntawv granular, pelletized thiab hmoov.Qhov ntau thiab tsawg sib txawv yog txhais rau kev siv sib txawv.Piv txwv li, hauv kev kho cua lossis roj av, kev txwv tsis pub ntws yog ntshuam, thiab yog li cov khoom ntxhib yog siv los txo qhov poob siab.Hauv kev kho cov kua dej, qhov twg cov txheej txheem tshem tawm qeeb qeeb, ces cov khoom siv zoo dua yog siv los txhim kho tus nqi, lossis kinetics, ntawm cov txheej txheem purification.

activated carbon ua haujlwm li cas?

Activated carbon ua haujlwm los ntawm cov txheej txheem ntawm adsorption.Qhov no yog ib qho kev nyiam ntawm cov molecule rau cov pa roj carbon ntau sab hauv los ntawm lub zog tsis muaj zog, hu ua London rog.Cov molecule tau tuav hauv qhov chaw thiab tsis tuaj yeem raug tshem tawm, tshwj tsis yog cov txheej txheem hloov pauv, piv txwv li cua sov lossis siab.Qhov no tuaj yeem pab tau raws li cov pa roj carbon activated tuaj yeem siv los mloog cov khoom ntawm nws qhov chaw uas tuaj yeem raug tshem tawm tom qab thiab rov qab los.Kev siv cov pa roj carbon activated rau kub rov qab yog ib qho piv txwv ntawm qhov no.

Qee qhov xwm txheej, cov pa roj carbon activated yog tshuaj kho kom tshem tawm cov pa phem thiab hauv qhov no, qhov tshwm sim tshwm sim feem ntau tsis zoo.

Activated carbon nto kuj tsis yog inert kiag li, thiab ntau yam txheej txheem catalytic tuaj yeem ua tiav siv thiab ua kom zoo dua ntawm thaj chaw sab hauv sab hauv.

Dab tsi yog activated carbon ntawm daim ntawv thov?

Activated Carbons muaj ntau yam kev siv los ntawm kev pom mus rau kev ua kom huv thiab dhau mus.

Nyob rau hauv xyoo tas los no, kev siv thiab zaus ntawm saj thiab tsw tsw hauv cov dej haus tau nce thoob plaws ntiaj teb.Tshaj li qhov teeb meem zoo nkauj rau cov neeg siv khoom, qhov no kuj tseem ua rau muaj qhov tsis paub tseeb txog qhov zoo thiab kev nyab xeeb ntawm dej.Cov tebchaw ua lub luag haujlwm rau kev saj thiab tsw tsw muaj teeb meem tuaj yeem muaj anthropogenic (kev lag luam lossis kev tawm hauv nroog) lossis keeb kwm lom neeg.Hauv qhov kawg, lawv yog tsim los ntawm microscopic kab mob xws li cyanobacteria.

Ob lub tebchaw feem ntau yog geosmin thiab 2-methylisoborneol (MIB).Geosmin, uas muaj lub ntiaj teb tsis hnov ​​tsw, feem ntau yog tsim los ntawm planktonic cyanobacteria (tso tseg hauv dej).MIB, uas muaj ntxhiab tsw, feem ntau yog tsim nyob rau hauv biofilm tsim nyob rau hauv pob zeb, dej nroj tsuag thiab sediment.Cov tebchaw no raug kuaj pom los ntawm tib neeg olfactory hlwb ntawm qhov tsis tshua muaj siab, txawm tias nyob hauv thaj tsam ntawm ob peb feem ntawm trillion (ppt, lossis ng / l).

Cov kev kho dej ib txwm tsis tuaj yeem tshem tawm MIB thiab geosmin kom qis dua lawv cov saj thiab tsw, uas ua rau kev siv cov pa roj carbon activated rau daim ntawv thov no.Ib txoj hauv kev zoo tshaj plaws ntawm kev ua haujlwm yog nrog cov hmoov activated carbon (PAC), uas yog dosed rau hauv cov dej ntws raws caij nyoog los tswj cov teeb meem saj & tsw.
