Mokhoa oa Electrolytic Oxidation bakeng sa ho Phekola Metsi a litšila a Sodium Cyanide

Selelekela

Cyanide - e nang le metsi a litšila, haholo-holo a tsoang ho Sodium Cyanide , ke bothata bo boholo ba tikoloho. Metsi a litšila a joalo a chefo haholo 'me haholo-holo a tsoa liindastering tse kang electroplating, tlhahiso ea khase, coking, metallurgy, ts'ebetso ea tšepe, faeba ea lik'hemik'hale, polasetiki, chefo e bolaeang likokoanyana le indasteri ea lik'hemik'hale. Ka metsing, ha a tsitsa 'me a ka bola habonolo. Li-cyanide tse sa pheleng le tsa tlhaho ke lintho tse chefo haholo. Mohlala, tekanyo e bolaeang ea cyanide 'meleng oa motho ke 0.18 g, 'me ea potassium cyanide ke 0.12 g. Ho phaella moo, mahloriso a bolaeang a cyanide ho litlhapi metsing a tloha ho 0.04 - 0.1 mg/L. Ka lebaka leo, mekhoa e sebetsang ea kalafo e hlokahala ka potlako ho fokotsa tšusumetso ea eona e kotsi tikolohong le bophelong ba batho.

The Basics of Electrolytic Oxidation for Cyanide - e nang le metsi a litšila

Mokhoa oa ho oxidation oa Electrolytic bakeng sa ho phekola metsi a litšila a Sodium cyanide o sebetsa ka molao-motheo oa ho sebelisa motlakase ho khanna lik'hemik'hale ho anode le cathode, ka hona o fetola cyanide metsing a litšila hore e be lintho tse seng kotsi haholo. Ts'ebetsong ena, cyanide e bonolo le cyanide e rarahaneng metsing a litšila li feta electrolysis.

Lits'oants'o tsa Anode

• Bakeng sa Simple Cyanide : Nakong ea karabelo ea mohato oa pele ho anode, simple cyanide e arabela ka matla le lintho tse ling tse metsing a litšila ho etsa motsoako o se nang chefo e ngata. Mokhahlelong oa bobeli o latelang, ho etsahala liketso tse peli. Karabelo e le 'ngoe e boetse e arola motsoako ona ho ba Carbon dioxide, naetrojene le metsi. Karabelo e 'ngoe e fella ka tlhahiso ea ammonium.

• Bakeng sa ho Kopanya Cyanide (Ho Nka Copper-Containing Complex e le Mohlala) : Ha coordinate cyanide, joalo ka li-complex tse nang le koporo, e fihla ho anode, e arabela ho etsa li-ion tsa koporo le motsoako o mong o seng chefo haholo. Ha letsoai la tafole le eketsoa ho electrolytic medium, ho etsahala liketso tse ling. Li-ion tsa chloride tse tsoang letsoai lia oxidized ho etsa chlorine e ntseng e hlaha. Chlorine ena e ntseng e hlaha ebe e arabela le cyanide le lintho tse ling metsing a litšila ho qhaqha metsoako ea cyanide hore e be lihlahisoa tse seng kotsi haholo, ho kenyeletsoa le li-ion tsa carbon dioxide, naetrojene le chloride.

Liketso tsa Cathode

Ho cathode, li-ion tsa haedrojene li fumana lielektrone 'me li etsa khase ea hydrogen. Bakeng sa tšepe - e nang le li-complexes tsa cyanide, tse kang tse nang le koporo, li-ion tsa koporo li fumana li-electrone 'me li ka kenngoa e le tšepe ea koporo. Tlas'a maemo a itseng, li-ion tsa koporo li ka boela tsa itšoara ka li-ion tsa hydroxide ho etsa copper hydroxide precipitate.

Lintlha tsa Bohlokoa Ts'ebetsong ea Electrolytic Oxidation

• Lisebelisoa tsa Electrode : Khetho ea thepa ea electrode ke ea bohlokoa. Maemong a mangata, tšepe e bobebe e ka sebelisoa e le thepa ea cathode. Leha ho le joalo, li-anode li hloka ho mamella tikoloho e thata ea electrochemical. Li-anode tse tsitsitseng ka tekanyo (DSA), tse entsoeng ka li-oxide tsa tšepe tse ntle 'me li hlahisoa ke lik'hamphani tse' maloa, li loketse hantle ts'ebeliso ena. Graphite e ka boela ea sebetsa e le thepa ea anode, empa e na le bothata ba ho sebelisoa butle-butle nakong ea ts'ebetso ea electrolysis.

• Taolo ea Mocheso : Mocheso oa mokelikeli o litšila nakong ea electrolysis o hloka ho laoloa ka hloko. Ka kakaretso o lokela ho bolokoa ka tlase ho 25 °C. Haeba mocheso o phahama haholo, chlorine e hlahisoang ke oxidation ea li-ion tsa chloride letsoai le ekelitsoeng e tla tsoa pele e ka arabela le cyanide, ka hona e fokotsa katleho ea ts'ebetso ea timetso ea cyanide.

• Ho Eketsa Ion ea Chloride : Ho eketsa li-ion tsa chloride metsing a litšila ho ka ntlafatsa oxidation ea electrolytic ea cyanide. Ka tloaelo, ho eketsa 1 - 2 g/L ea li-ion tsa chloride ho lekane. Maemong a mang, ho eketsa letsoai le tloaelehileng (sodium chloride) ka bongata ba 25 g ka litara ho mokelikeli o litšila ho bontšitsoe ho thusa ka katleho timetsong ea cyanide ka electrolytic.

Melemo ea Ts'ebetso ea Electrolytic Oxidation

• Bokgoni bo Phahameng ba ho Sebetsa Metsi a Ditshila a nang le Metsi a Mangata : Ts'ebetso ya ho qhibilihisa oli ka motlakase e sebetsa haholo bakeng sa ho phekola metsi a ditshila a nang le cyanide e nang le metsi a mangata, jwalo ka a fumanwang merafong ya kgauta. E ka fokotsa haholo metsi a ditshila a nang le cyanide.

• Tlhahiso ea Mefuta e Reactive Sebakeng : Nakong ea electrolysis, mefuta e arabelang joalo ka chlorine e sa tsoa hlaha e hlahisoa ka har'a sistimi. Sena se felisa tlhoko ea ho eketsa ka ntle metsoako e ka bang kotsi le e turang ea oxidizing ka bongata bo boholo.

• Ho tenyetseha : Ts'ebetso e ka fetoloa ho latela sebopeho se itseng sa metsi a litšila. Ka ho laola liparamente tse kang ho ba le bongata ba hona joale, motlakase, le ho eketsoa ha letsoai le itseng, ts'ebetso ea oxidation ea electrolytic e ka ntlafatsoa bakeng sa mefuta e fapaneng ea cyanide - e nang le metsi a litšila, ebang a na le metsoako e bonolo kapa e rarahaneng ea cyanide.

fihlela qeto e

Mokhoa oa ho ntša metsi ka motlakase o fana ka tharollo e tšepisang bakeng sa ho phekola metsi a litšila a sodium cyanide . Ka ho utloisisa liketso tsa lik'hemik'hale tse hlahang ho anode le cathode, ho khetha thepa ea electrode ka hloko, ho laola mocheso, le ho eketsa bongata bo loketseng ba li-ion tsa chloride, mokhoa ona o ka tlosa tšilafalo ea cyanide metsing a litšila ka katleho. Ha liindasteri li ntse li tsoela pele ho batla litsela tse tsitsitseng le tse sebetsang tsa ho laola litšila tsa tsona, mokhoa oa ho ntša metsi ka motlakase o ka 'na oa sebelisoa haholo kalafong ea metsi a litšila a nang le cyanide. Leha ho le joalo, lipatlisiso le nts'etsopele e eketsehileng li ntse li hlokahala ho ntlafatsa ts'ebetso, ho fokotsa litšenyehelo, le ho ntlafatsa katleho ea eona ka kakaretso le botsoalle ba tikoloho.
