Mokhoa oa kalafo oa metsi a litšila a nang le cyanide le metsi a litšila a sodium cyanide

Sebakeng sa ts'ireletso ea tikoloho, phekolo ea cyanide - e nang le metsi a litšila le Sodium cyanide metsi a litšila esale e le taba ea bohlokoa. Ka tsoelo-pele e potlakileng ea tlhahiso ea indasteri, haholo-holo indastering e kang ea electroplating, metallurgy, le lik'hemik'hale, ho ntšoa ha cyanide - e nang le metsi a litšila ho ntse ho eketseha selemo le selemo, ho baka tšokelo e tebileng tikolohong. Ka hona, ho lekoa ha mekhoa ea kalafo e sebetsang hantle, ea moruo, le e baballang tikoloho bakeng sa cyanide - e nang le metsi a litšila ke ea bohlokoa haholo.

Litšobotsi le Likotsi tsa Cyanide - E na le Metsi a litšila

Cyanide - e nang le metsi a litšila hangata e na le lintho tse phahameng tsa cyanide, tse teng metsing ka mefuta e sa lefelloeng kapa e rarahaneng. Har'a tsona, li-complexes tsa tšepe - cyanide, tse kang koporo - cyanide complexes le zinki - cyanide complexes, li tsitsitse ebile li thata ho li tlosa ka mekhoa e tloaelehileng ea phekolo. Ho phaella moo, metsi a litšila a ka 'na a e-na le li-ion tse ling tse boima, lintho tse phelang, li-acids, alkalis le lintho tse ling, tse nang le motsoako o rarahaneng, o eketsang bothata ba phekolo. Ho tsoa ha cyanide - e nang le metsi a litšila ha e silafatse metsi feela empa e boetse e bokellana ka har'a ketane ea lijo, e leng se bakang tšokelo ea nako e telele tikolohong ea tikoloho le bophelo bo botle ba batho.

Theknoloji ea Phekolo ea Cyanide - E Nang le Metsi a litšila

Ka lebaka la litšoaneleho tsa cyanide - e nang le metsi a litšila, mekhoa ea phekolo e sebelisoang haholo-holo e sebelisoang hona joale e kenyelletsa mekhoa ea phekolo ea oxidation, mekhoa ea phekolo ea electrolytic, mekhoa ea phapanyetsano ea ion, mekhoa ea phekolo ea likokoana-hloko, le tšebeliso e kopantsoeng ea mekhoa e mengata ea theknoloji.

Mekhoa ea Phekolo ea Oxidation

Alkaline Chlorination Mokhoa

Tlas'a maemo a alkaline (hangata ka boleng ba pH bo pakeng tsa 10 le 11), di-oxidant tse kang chlorine kapa sodium hypochlorite di eketsoa ho kopanya dintho tsa cyanide le nitrogen e seng chefo le k'habone dioxide. Mokhoa ona o bonolo ho o sebedisa, o na le ditlamorao tse tsitsitseng tsa kalafo, mme meriana e fumaneha habonolo mme e theko e tlase haholo. Leha ho le jwalo, e ka baka tshilafatso ya bobedi mme e na le phello e itseng ya ho senya disebedisweng.

Hydrogen Peroxide Oxidation Mokhoa

Tlas'a maemo a asiti kapa alkaline, hydrogen peroxide e sebelisoa e le oxidant ho oxidize lintho tsa cyanide ho etsa naetrojene le metsi. E loketse haholo ho hloekisa metsi a litšila ka lintho tse phahameng tsa cyanide, empa litšenyehelo tsa kalafo li holimo, 'me maemo a karabelo a hloka ho laoloa ka thata.

Mokhoa oa Ozone Oxidation

Ho sebelisa thepa e matla ea oxidizing ea ozone, lintho tsa cyanide li tšeloa ka lintho tse seng chefo. Ts'ebetso ea kalafo e phahame mme ha ho na tšilafalo ea bobeli, empa matsete a lisebelisoa le litšenyehelo tsa ts'ebetso li holimo.

Fenton Oxidation Mokhoa

Fenton reagent e entsoeng ka hydrogen peroxide le matsoai a tšepe e sebelisoa bakeng sa oxidation ea lik'hemik'hale ho senya lintho tsa cyanide ka katleho.

Mokhoa oa Phekolo ea Electrolytic

Electrochemical oxidation reaction e sebelisoa ho senya lintho tsa cyanide metsing a litšila. Tlas’a maemo a itseng, li-ion tsa cyanide tse metsing a litšila li tšeloa ka carbon dioxide, nitrogen le ammonia. E loketse ho hloekisa metsi a litšila ka li-ion tse phahameng tsa cyanide, empa e sebelisa matla a motlakase 'me e ka hlahisa khase e chefo ea cyanogen chloride.

Ion - Mokhoa oa ho Fetolana

Matla - li-anion tsa motheo - li-resin tsa phapanyetsano li sebelisetsoa ho fapanyetsana le li-ion tsa cyanide ka tharollo, ho finyella ho tlosoa ha li-ion tsa cyanide. E loketse kalafo ea cyanide - e nang le metsi a litšila a nang le likhahla tse mahareng le tse tlase, e na le ts'ebetso e phahameng ea kalafo, 'me e khona ho khutlisa li-ion tsa bohlokoa tsa tšepe, empa litšenyehelo tsa kalafo li batla li phahame.

Mokhoa oa Phekolo ea Likokoana-hloko

Ka ho senyeha ha likokoana-hloko, lintho tsa cyanide li fetoloa lintho tse seng chefo kapa tse tlaase - tse chefo. E na le botsoalle ba tikoloho ebile e tšoarella, empa e hloka maemo a loketseng a tikoloho (joalo ka mocheso, pH ea boleng, joalo-joalo) le nako e telele ea phekolo. Mekhoa e tloaelehileng ea phekolo ea likokoana-hloko e kenyelletsa mokhoa oa sludge o kentsoeng le mokhoa oa biofilm.

Mekhoa e Kopantsoeng

Ka lebaka la ho rarahana ha cyanide - e nang le metsi a litšila, ts'ebeliso e kopaneng ea mahlale a mangata hangata e amoheloa. Ka mohlala, "alkaline chlorination method + ion - exchange method", "electrolytic treatment method + ion - exchange method", "hydrogen peroxide oxidation method + biological treatment method", joalo-joalo Ka mekhoa e kopantsoeng, ka botebo ho phekoloa ha metsi a litšila ho ka finyelloa, 'me boleng ba metsi a litšila bo ka ntlafatsoa.
