Imisipha yezimayini zegolide iqukethe inani elikhulu le-cyanide. Kodwa-ke, ama-ions forrrous e-sulfate ye-ferrous angaphendula ngamakhemikhali nge-cyanide yamahhala emisindweni, futhi akhiqize ama-cyanide angenhla kanye nezinye izinto. Lokhu kuphendula kungathinta imiphumela yayo yokusabela ngaphansi kwezimo ezithile zangaphandle. Isibonelo, ukwelashwa kwamanzi angcolile aqukethe ama-cyrinis nge-sulfate ethambile ngaphansi kokushisa okuphezulu, inani eliphansi le-PH, kanye ne-ultraviolet irradiation kuzothinta ukusabela. I-Ferrous Cyanide ingazinzile kakhulu, futhi ngesikhathi senqubo yokubuyiselwa emuva, isixazululo se-Ferrous Cyanide kalula seliphuma, okwenza ukungcoliswa okukhulu kwamanzi angaphansi komhlaba. Masikwazi ukuhlaziya ngokuqondile inqubo yokusabela kanye nemiphumela yokungeza i-Cyanide ku-sulfate ye-Ferrous. Asenzeni lokhu ucwaningo lokufaka i-Cyanide lapho kune-sulfate eningi ende. Lokho kusho ukuthi, lapho kufakwa i-sulfate eyeqile kwikhambi le-cyanide, i-cyanide izophenduka ibe yi-infolcuble Fe4 [FE (CN) 6] 3, esivame ukubiza i-Prussian Blue. Vele, enqubweni yokwelashwa kwemisila ezimayini zegolide, ezinye izinkampani azikhethi ukwengeza i-sulfate ye-Ferrous ukuze zithole ukwelashwa, kepha khetha ukwengeza i-sulfide ye-ferfous. Ezinye izinkampani zikhetha ukwengeza i-iron ne-zethusi ngasikhathi sinye ukukhiqiza i-cyanide ye-white insoluble fernous. I-Ferrous Iron imunca ngokushesha umoya-mpilo emoyeni, iphenduka ibe mnyama okwesibhakabhaka, bese ithola amafomu fercyanide.
Kungaphethwa ngokuthi izivivinyo ezingcono kakhulu zokususa i-cyanide kwisixazululo nge-ferrous sulfate ukuthola inqubo ekhiqiza amakhompiyutha ancibilikayo futhi angena ngaphakathi. Ngesikhathi sokuhlola, sabala isilinganiso se-molar semiphumela yokusabela ye-ferrous sulfate ne-cn-. Okokuqala, isilinganiso sibalwe ngokusho kukaStoichiometry kwakungu-0.39, kepha isilinganiso esifanele sokuhlaselwa esikutholile ngesibalo sasingu-0.5. . I-PH efanelekile yokuthola i-prussian Blue i-5.5 kuye ku-6.5. Ngokuvamile, i-oxygen can oxidize ist iron ion ukwakha i-fercyanide kanye ne-fercyanide ion, engathandeki kakhulu ekususweni kwe-cyanide. Ngoba i-Ion ye-Fricyanate ayizinzile kakhulu ngaphansi kwezimo ze-acidic, izokwenza ifomu le-Ferrous Pentackationano eyinkimbinkimbi [FE (CN) 5h2o] 3-, oxides axidized to Fercyanate Ion FE (CN). ) 63-. Lokhu kusabela ngokuyisisekelo kwenzeka kumanani we-PH ngezansi kwe-4. Ekugcineni, ekugcineni safinyelela esiphethweni sendlela yokwelashwa ye-Folf Imayini yegolide, isimo esihle semvelo sokusebenzisa i-cyanide kusuka kumisila Inani le-PH le-5.5 kuye ku-6.5. Inani lezinombolo lilifanele kakhulu, futhi isilinganiso se-FE to CN-0.5 silungele kakhulu ukucubungula.
