Mfundo ya activated carbon adsorption

1.Kutengera kapangidwe kake ka pore

Activated mpweya ndi mtundu wa microcrystalline mpweya zinthu makamaka zopangidwa carbonaceous zinthu ndi maonekedwe wakuda, anayamba mkati pore dongosolo, lalikulu enieni pamwamba m'dera ndi adsorption amphamvu mphamvu. zinthu yaying'ono pores, adzakhala kukod pambuyo pamwamba kufika pa 800-1500 lalikulu mamita, ntchito.Ndiko kuti, m'kati padziko pores mu adamulowetsa mpweya tinthu kukula kwa njere ya mpunga akhoza kukhala Kukula kwa chipinda chochezera. Izi ndizomwe zimatukuka kwambiri, monga mawonekedwe a pore a capillary, kotero kuti activated carbon imakhala ndi ntchito yabwino ya adsorption.

Acidated Carbon Adsorption ndi mchitidwe wa kudzikundikira kwa gasi kapena madzi pamwamba pa mpweya wokhazikika, chinthu cholimba cha inert.Njirayi imagwiritsidwa ntchito kuchotsa zowononga zosiyanasiyana, zosungunuka m'madzi, mpweya, ndi mitsinje ya mpweya.

2. Mphamvu ya adsorption pakati pa mamolekyu

Imadziwikanso kuti "van der Waals gravity" .Ngakhale kuthamanga kwa kayendedwe ka maselo kumakhudzidwa ndi kutentha ndi zinthu, nthawi zonse kumayenda mu microenvironment.activated carbon chifukwa cha kukopana pakati pa mamolekyu, pamene molekyu inayendetsedwa ndi mpweya wamkati wamkati. mu adamulowetsa mpweya wamkati pore, chifukwa cha kukopana pakati pa mamolekyu, zidzachititsa kuti mamolekyu ambiri amakopeka, mpaka kudzazidwa adamulowetsa mpweya wamkati pore.

The adamulowetsa mpweya adsorption mfundo: Anapangidwa mu tinthu pamwamba wosanjikiza bwino pamwamba ndende, ndiye zosafunika organic zinthu adsorbed kuti adamulowetsa mpweya particles, koyamba mkulu adsorption kwenikweni.Koma m'kupita kwa nthawi, adamulowetsa mpweya adsorption mphamvu adzakhala wofooka kwa madigiri osiyanasiyana, zotsatira adsorption komanso decreases.Ngati Aquarium madzi turbidity, mkulu organic zili m'madzi, adamulowetsa mpweya posachedwapa adzakhala imfa ya kusefera ntchito.The activated carbon ayenera kuyeretsa nthawi zonse kapena kusintha.
