Kenyelletso ea Khabone e Kentsoeng le Lits'ebetso tsa Bohlokoa
Selelekela
Activated carbon ke mofuta oa carbon o nang le masoba a mangata haholo o nang le sebaka se seholo sa bokaholimo, e leng se etsang hore e be ntho e khahlang haholo bakeng sa litšila tse fapaneng. Bokhoni ba eona ba ho tšoasa litšila bo entse hore ho sebelisoe haholo tikolohong, indastering le lits'ebetsong tsa bongaka. Sengoliloeng sena se hlahloba likarolo tsa eona le lisebelisoa tsa bohlokoa ka botlalo.
Mekhoa ea Tlhahiso
Khabone e kentsoeng e entsoe ka thepa e nang le khabone e ngata joalo ka likhetla tsa coconut, patsi, mashala, ka lits'ebetso tse peli tse kholo:
- Carbonization- Ho futhumatsa thepa e tala sebakeng se se nang oksijene ho tlosa metsoako e sa tsitsang.
- Tshebetso- Ho ntlafatsa porosity ka:
Tshebetso ya mmele(ho sebelisa mouoane kapa CO₂)
Ts'ebetso ea lik'hemik'hale(ho sebelisa li-acids kapa metheo e kang phosphoric acid kapa potasiamo hydroxide)
Khetho ea lisebelisoa le mokhoa oa ho kenya ts'ebetsong o khetholla thepa ea ho qetela ea carbon.
Classification ea Activated Carbon
Activated carbon e ka aroloa ho latela:
1. Sebopeho sa 'Mele
- Powdered Activated Carbon (PAC)- Likaroloana tse ntle (<0.18 mm) tse sebelisoang kalafong ea mokelikeli, joalo ka tlhoekiso ea metsi le decolorization.
- Granular Activated Carbon (GAC)- Li-granules tse kholoanyane (0.2-5 mm) tse sebelisoang lits'ebetsong tsa khase le metsi.
- Pelletized Activated Carbon- Li-pellets tsa cylindrical tse hatelitsoeng bakeng sa lits'ebetso tsa moea le mouoane.
Activated Carbon Fiber (ACF)- Lesela kapa foromo e entsoeng, e sebelisoang ho limaske tse khethehileng tsa khase le ho hlaphoheloa ha solvent.
- 2. Mohloli oa Boitsebiso
- Coconut Shell-E Thehiloe- Microporosity e phahameng, e loketseng khase ea adsorption (mohlala, li-respirators, ho hlaphoheloa ha khauta).
- E Thehiloe ka Lehong- Li-pores tse kholo, tse atisang ho sebelisoa ho nyenyefatsa lino tse kang li-syrups tsa tsoekere.
- E Thehiloe ka Mashala- E theko e tlaase, e sebelisoang haholo moeeng oa indasteri le phekolo ea metsi.
3. Pore Size
- Microporous (<2 nm)- E sebetsa hantle bakeng sa limolek'hule tse nyane (mohlala, polokelo ea khase, ho tlosoa ha VOC).
- Mesoporous (2–50 nm)- E sebelisoa ho adsorption e kholo ea molek'hule (mohlala, ho tlosa dae).
- Macroporous (> 50 nm)- E sebetsa joalo ka sesefa pele ho thibela ho koala kalafo ea mokelikeli.
- Tlhoekiso ea Metsi a Noang- E tlosa chlorine, litšila le monko o mobe.
- Phekolo ea Metsi a litšila- E sefa litšila tsa indasteri, meriana le litšepe tse boima (mohlala, mercury, lead).
- Filtration ea Aquarium- E boloka metsi a hloekileng ka ho sebelisa chefo.
2. Tlhoekiso ea Moea le Khase
- Lisefe tsa Moea tse ka Hare- E tšoasa metsoako ea lintho tse phelang (VOCs), mosi le menko.
- Ho Hloekisa Khase ea Liindasteri- E tlosa lintho tse silafatsang tse kang hydrogen sulfide (H₂S) ho tsoa mesing e hloekisang.
- Likopo tsa likoloi- E sebelisoa ka har'a lifensetere tsa moea tsa khabinete ea koloi le lits'ebetso tsa ho khutlisa mouoane oa mafura.
3. Tšebeliso ea Meriana le Meriana
- Kalafo ea Chefo le Ho Feta Tetello– Emergency antidote bakeng sa overdose ea lithethefatsi (mohlala, matlapa a mashala a kentsoeng).
- Liaparo Tsa Maqeba– Antimicrobial activated carbon fibers thibela tšoaetso.
4. Indasteri ea Lijo le Lijo
- Decolorization- E hloekisa tsoekere, oli ea meroho le lino tse tahang.
- Ntlafatso ea Tatso- E tlosa litatso tse sa batleheng metsing a nooang le lero.
5. Lisebelisoa tsa Indasteri le Tse khethehileng
- Khauta Recovery- E ntša khauta ho tsoa litharollong tsa cyanide merafong.
- Solvent Recycling- E khutlisetsa acetone, benzene le lik'hemik'hale tse ling.
- Polokelo ea Khase- E boloka methane le hydrogen ts'ebelisong ea matla.
Qetello
Activated carbon ke sesebelisoa se feto-fetohang se nang le likarolo tsa bohlokoa ts'ireletso ea tikoloho, tlhokomelo ea bophelo bo botle le lits'ebetso tsa indasteri. Katleho ea eona e itšetlehile ka sebōpeho sa eona, lisebelisoa tsa mohloli, le sebopeho sa pore. Lintlafatso tsa nako e tlang li ikemiselitse ho ntlafatsa ts'ebetso ea eona, joalo ka ho e hlahisa ka litšila tsa temo kapa ho ntlafatsa mekhoa ea ntlafatso.
Ha liqholotso tsa lefats'e joalo ka khaello ea metsi le tšilafalo ea moea li ntse li tota, khabone e kentsoeng e tla tsoela pele ho bapala karolo ea bohlokoa. Lits'ebetso tsa nako e tlang li ka hola ho ea libakeng tse ntseng li hlaha joalo ka ho ts'oaroa ha khabone bakeng sa phokotso ea phetoho ea maemo a leholimo kapa lits'ebetso tse tsoetseng pele tsa ho hloekisa bakeng sa ho tlosa microplastic.
