Mehloli ea Geological

Iron sulfide haholo-holo e tsoa mehloling ea jeoloji. Pyrite, minerale e tloaelehileng ea iron sulfide, e ajoa haholo mafikeng a sedimentary le mobung. Boemo ba leholimo le khoholeho ea libopeho tsena li lokolla li-ion tsa tšepe le sulfide metsing, e leng se lebisang ho thehoeng ha ho qhibiliha. sulfide ea tšepe kapa pula ea eona e le mekhahlelo e tiileng. Mefuta e ikhethileng le likhakanyo li ipapisitse le lintlha tse kang pH, bokhoni ba redox, le boteng ba li-ion tse ling. Ho utloisisa mehloli ena ea jeoloji ho bohlokoa bakeng sa ho bolela esale pele bokhoni ba sulfide ea tšepe tšilafalo mekhoeng e khethehileng ea metsi. Ka mohlala, libaka tse nang le majoe a mangata a nang le pyrite li kotsing haholo sulfide ea tšepe tšilafalo metsing a ka tlas'a lefatše.

Mekhoa ea Likokoana-hloko

Mekhoa ea likokoana-hloko e boetse e kenya letsoho ho sulfide ea tšepe sebopeho metsing. Libaktheria tse fokotsang sulfate (SRB) ke likokoana-hloko tse sebelisang sulfate e le moamoheli oa elektronike maemong a anaerobic, a hlahisang li-ion tsa sulfide joalo ka sehlahisoa. Joale li-ion tsena tsa sulfide li sebetsa ka tšepe e qhibilihisitsoeng, e lebisang ho thehoeng ha ferrous sulfide (FeS) kapa metsoako e meng ea tšepe ea sulfide. Mosebetsi oa SRB o susumetsoa ke lintlha tse kang ho fumaneha ha lintho tse phelang, mocheso le pH. Maemong a mangata, lits'ebetso tsa baeloji li susumetsa haholo ho tsepamisa maikutlo le mefuta ea sulfide ea tšepe litsamaisong tsa metsing, haholo tikolohong ea anaerobic joalo ka sediments kapa libaka tse emeng tsa metsi.

Thepa le Liphello tsa Iron Sulfidi ka Metsing

Iron sulfide ka metsing e bonts'a thepa e fapaneng e amang boleng ba metsi haholo le lits'ebetso tsa indasteri. Ho qhibiliha ha metsoako e fapaneng ea iron sulfide ho fapana haholo ho latela pH le maemo a redox. Ka mohlala, ferrous sulfide (FeS) ha e khone ho qhibiliha tlas'a maemo a sa nke lehlakore kapa a alkaline hanyenyane, ha mefuta e mengata e rarahaneng e ka 'na ea bontša litšobotsi tse fapaneng tsa ho qhibiliha. Boteng ba sulfide ea tšepe ka metsing ho ka baka mathata a 'maloa:

Mathata a Boleng ba Metsi

Maemo a phahameng a sulfide ea tšepe e ka fana ka tatso e sa thabiseng le monko o sa thabiseng metsing, e leng se etsang hore a se ke a tšoanela ho nooa le ho sebelisoa malapeng. Ho ba teng ha hydrogen sulfide (H₂S), sehlahisoa sa gaseous sa ho bola ha iron sulfide, se kenya letsoho monkong o mobe. Ho feta moo, iron sulfide e ka silafatsa lipeipi tsa metsi le masela, e bakang mathata a botle. Sena se na le bothata haholo maemong a indasteri a hlokang metsi a boleng bo holimo.

Liphello Tsa Liindasteri

Libakeng tsa indasteri, sulfide ea tšepe e ka baka mathata a maholo. E ka senya liphaephe, li-reactor le lisebelisoa tse ling, e leng se lebisang ho fokotseng ts'ebetso le ho eketseha ha litšenyehelo tsa tlhokomelo. Iron sulfide e ka boela ea baka lintho tse senyang, tse senyang likarolo tsa tšepe. Mekhoa e mengata ea indasteri e hloka metsi a nang le likhahla tse tlaase haholo tsa ho qhibiliha sulfide ea tšepe, e batlang mekhoa e thata ea ho hloekisa metsi.

Ho fumanoa le ho Lokisoa ha Iron Sulfidi ka Metsing

Tlhahlobo e nepahetseng le tokiso e sebetsang ke tsa bohlokoa bakeng sa ho laola sulfide ea tšepe ka metsing. Ho sebelisoa mekhoa e mengata ho fumana le ho tlosa motsoako ona phepelong ea metsi.

Mekhoa ea ho Khetholla

Ho sebelisoa mekhoa e fapaneng ea tlhahlobo ho fumana iron sulfide ka metsing. Tsena li kenyelletsa mekhoa ea colorimetric, atomic absorption spectroscopy (AAS), le plasma mass spectrometry (ICP-MS) e kopantsoeng hantle, e 'ngoe le e' ngoe e fana ka maemo a fapaneng a kutlo le boikhethelo.

Maano a Tokiso

Ho na le litsela tse 'maloa tsa ho lokisa tse teng bakeng sa ho tlosa kapa ho fokotsa sulfide ea tšepe ho tsoa metsing. Tsena hangata li kenyelletsa mekhoa ea oxidation, pula, le mekhoa ea ho sefa. Mekhoa ea oxidation e fetoha e qhibilihisitsoeng sulfide ea tšepe hore e be mefuteng e fokolang e qhibilihang, e thusang ho tlosoa ha tsona ka pula kapa ka ho sefa. Mekhoa e ikhethileng e kenyelletsa moea, oxidation ea lik'hemik'hale e sebelisang li-oxidizing agents tse kang chlorine kapa potassium permanganate, le bioloji oxidation e sebelisang likokoana-hloko tse khethehileng. Mekhoa ea ho sefa, joalo ka ho sefa lehlabathe, activated carbon adsorption, le membrane filtration, e ka nts'etsa pele ho tlosa iron sulfide metsing.
