Alkaline Chlorination

Ho sebelisa chlorination ea alkaline ke e 'ngoe ea mekhoa e sebelisoang haholo bakeng sa ho phekola metsi a litšila a nang le cyanide. Ts'ebetsong ena, metsoako e nang le chlorine kapa chlorine (joalo ka sodium hypochlorite) e eketsoa metsing a litšila tlas'a maemo a alkaline. Karabelo e etsahala ka mehato e 'meli. Ea pele, cyanide e oxidized ho ea cyanogen chloride, ebe cyanogen chloride e hydrolyzes ho etsa cyanate. Qetellong, li-ion tsa cyanate li hydrolyzed hape ho hlahisa ammonia le k'habonetes. Ts'ebetso ea setso ea alkaline chlorination hangata e hloka pH e phahameng ea hoo e ka bang 10.5 le bokhoni bo phahameng ba ho fokotsa oxidation (ORP) ba + 600 mV. Leha ho le joalo, ke ts'ebetso e matla ea lik'hemik'hale, e jang sodium hypochlorite e ngata. Mohlala, ho hlokahala ligalone tse ka bang 23 tsa tharollo ea sodium hypochlorite ea 12.5% ​​ho senya ounce e le 'ngoe ea cyanide.

Phekolo ea Likokoana-hloko

Phekolo ea likokoana-hloko ea cyanide - e nang le metsi a litšila e kenyelletsa tšebeliso ea likokoana-hloko tse itseng. Libaktheria tsa Aerobic tse kang Pseudomonas, Alcaligenes le Achromobacteria li ka oxidize cyanide ho cyanate. Ka mor'a moo, ion ea cyanate e fetoloa ka biologically ho ammonia le bicarbonate. Mokhoa ona o sebetsa hantle ha motsoako oa cyanide metsing a litšila o le tlase haholo. Leha ho le joalo, e hloka taolo e hlokolosi ea maemo a tikoloho joalo ka mocheso, pH, le boteng ba limatlafatsi tse loketseng ho netefatsa kholo le mosebetsi oa likokoana-hloko.

Mokhoa oa Acidification

Mokhoa oa asiti ke mokhoa oa khale oa ho phekola cyanide e phahameng - e nang le metsi a litšila liindastering tse kang merafo ea khauta le cyanide electroplating. Ka mokhoa ona, metsi a litšila a na le asiti e le hore a lokolle khase ea hydrogen cyanide, e ka khutlisoang kapa ea phekoloa hape. Mokhoa ona o na le molemo oa ho khona ho khutlisa cyanide metsing a litšila, empa o hloka ho tšoaroa ka hloko ha khase ea hydrogen cyanide e lokolotsoeng ho thibela tšilafalo ea tikoloho le ho netefatsa polokeho.

Mekhoa e Tsoetseng Pele ea Oxidation (AOPs)

Mekhoa e tsoetseng pele ea oxidation, joalo ka ozone oxidation le ultraviolet (UV) - catalyzed oxidation, li bontšitse bokhoni bo boholo kalafong ea Sodium cyanide - metsi a silafetseng. Ozone oxidation e ka senya cyanide hore e be lintho tse seng kotsi haholo. Molek'hule ea ozone e kopana le cyanide, e roba maqhama a lik'hemik'hale ebe e e fetola metsoako e tsitsitseng haholoanyane. UV - catalyzed oxidation, ka lehlakoreng le leng, hangata e sebelisa li-catalyst hammoho le khanya ea ultraviolet le li-oxidants joalo ka hydrogen peroxide. Mohlala, tsamaisong ea UV - H₂O₂, lebone la ultraviolet le kenya hydrogen peroxide tšebetsong, le hlahisa li-radicals tse sebetsang haholo tsa hydroxyl tse ka senyang cyanide kapele. Ts'ebetso tsena hangata li sebetsa hantle haholo 'me li ka fihlella likhakanyo tse tlase tsa masala a cyanide ha li bapisoa le mekhoa ea setso.

Mekhoa e thehiloeng ho Nanotechnology

Nanotechnology e ntse e hlahella e le sebaka se tšepisang sa ho ntlafatsa taolo ea tšilafalo ea cyanide. Li-nanomaterials, tse kang nanocatalysts, li ka ntlafatsa litekanyetso tsa karabelo ea lits'ebetso tsa ho senyeha ha cyanide. Mohlala, li-nanocatalyst tse ling tse thehiloeng ho tšepe li ka khothaletsa oxidation ea cyanide ka mokhoa o ikhethileng tlas'a maemo a bobebe. Ho feta moo, li-membrane tsa nanofiltration li ka sebelisoa ho arola cyanide le litšila tse ling metsing. Li-membrane tsena li na le li-pores sebakeng sa nanometer, tse lumellang ho tlosoa ka katleho ha limolek'hule tse nyenyane le li-ion, ho akarelletsa le cyanide, ha li ntse li boloka lintho tsa bohlokoa le ho fokotsa boholo ba litšila tse hlahisoang.

Indastering ea Merafo

Merafong ea khauta, kae sodium cyanide e atisa ho sebelisoa bakeng sa ho ntša khauta, theknoloji ea ho laola tšilafalo ke ea bohlokoa ka ho fetisisa. Mohlala, mesebetsi e meng e meholo ea merafo e amohetse motsoako oa alkaline chlorination le kalafo ea baeloji. Taba ea pele, ts'ebetso ea alkaline chlorination e sebelisoa ho fokotsa cyanide e phahameng ka har'a metsi a litšila ho isa boemong bo itseng. Joale, metsi a litšila a tsoela pele ho phekoloa ka biologically ho finyella litekanyetso tse thata tsa ho qhala tikoloho. Maemong a mang, ho ntse ho lekoa mahlale a macha joalo ka UV - catalyzed oxidation. Merafo e libakeng tse hlokometsoeng ke tikoloho e khothaletsoa ka ho khetheha ho amohela mekhoa e tsoetseng pele le e sebetsang haholoanyane ea ho laola tšilafalo ho fokotsa tšusumetso tikolohong e haufi le tikoloho.

Ka Phekolo ea Metsi a Litšila ea Liindasteri

Liindasteri tsa electroplating tse sebelisang libate tsa cyanide-based plating le tsona li hlahisa bongata bo boholo ba cyanide - e nang le metsi a litšila. Limela tse ngata tsa sejoale-joale tsa electroplating li kentse sebakeng - lits'ebeletso tsa kalafo ea metsi a litšila. Hangata ba sebelisa letoto la mehato ea phekolo, ho qala ka pula ea litšepe tse boima tse amanang le li-complexes tsa cyanide, tse lateloang ke ho timetsoa ha cyanide e sa lefelloeng ho sebelisa mekhoa e kang alkaline chlorination kapa mekhoa e tsoetseng pele ea oxidation. Limela tse ling li boetse li kentse ts'ebetsong mekhoa e tsoelang pele ea ho beha leihlo ho netefatsa hore metsi a litšila a hloekisitsoeng a finyella litlhoko tsa taolo pele a kenngoa tsamaisong ea likhoerekhoere kapa metsing a ka holim'a metsi.

Mathata le Maikutlo a Bokamoso

Leha ho na le boteng ba mahlale a fapaneng a taolo ea tšilafalo ea sodium cyanide, liphephetso tse 'maloa li ntse li le teng. E 'ngoe ea liqholotso tse kholo ke litšenyehelo tse phahameng tse amanang le mekhoa e meng ea phekolo e tsoetseng pele, haholo-holo bakeng sa likhoebo tse nyenyane le tse mahareng. Ho phaella moo, phekolo ea cyanide e rarahaneng - e nang le metsi a litšila, e ka 'nang ea e-ba le motsoako oa metsoako ea cyanide le litšila tse ling, e hloka mekhoa ea phekolo e sebetsang hantle le e fapaneng.

Ha re sheba bokamoso, lipatlisiso tse ling le nts'etsopele lia hlokahala ho ntlafatsa ts'ebetso le litšenyehelo - katleho ea mahlale a teng. Sena se ka kenyelletsa ho ntlafatsa maemo a karabelo, nts'etsopele ea li-catalyst tse tsitsitseng le tse sebetsang hantle, le ho kopanya mekhoa e fapaneng ea kalafo. Ho feta moo, phuputso ea likhopolo tse ncha le tse ncha tsa phekolo, tse kang tšebeliso ea likokoana-hloko tse entsoeng ka liphatsa tsa lefutso bakeng sa ho senyeha ha cyanide e matlafalitsoeng kapa ho sebelisoa ha lisebelisoa tse ncha tse nang le thepa e ikhethang bakeng sa ho tlosoa ha cyanide, ho na le tšepiso e kholo ea ho laola tšilafalo ea sodium cyanide ka nako e telele.

Qetellong, lipatlisiso le ts'ebeliso ea mahlale a taolo ea tšilafalo ea sodium cyanide li bohlokoa bakeng sa ho sireletsa tikoloho le bophelo bo botle ba batho. Ntlafatso e tsoelang pele le ntlafatso ea theknoloji ena e tla bapala karolo ea bohlokoa ntlafatsong ea moshoelella ea indasteri le ts'ireletso ea tikoloho.
