Kushandisa ferrous sulfate kurapa miswe mugoridhe mini

Misungo yegoridhe minizi ine huwandu hukuru hweCyanide. Nekudaro, zvidimbu zveshungu mumubheji sulfate zvinogona kuita nemakemikari neyemahara cyanide mumisungo, uye gadzira madhimoni echinyakare uye zvimwe zvinhu. Kuita uku kunogona kukanganisa maitiro ayo anoguma nemamwe mamiriro ekunze. Semuenzaniso, kurapwa kweanotenga-kune marara ane marara ane sulfate pasi pekudziya kwakanyanya, akaderera pH kukosha, uye Ultraviolet kurira kuchakanganisa maitiro. Mberi Ngativerengei zvakananga maitiro ekuita uye mhedzisiro yekuwedzera cyanide kuenda ku ferusus sulfate. Ngatiitei muyedzo wekuwedzera cyanide kana paine yakawanda sulrous sulfate. Ndozviti, kana yakanyanyisa ferrous sulfate inowedzerwa kune yeCyanide Solution, Cyanide ichashanduka kuita insoluble precipotitate fe4 [fe (cn) 6] 3, yatinowanzo fonera prussian bhuruu. Ehezve, mukushandiswa kwemisungo kurapwa mune goridhe migodhi, mamwe makambani haasarudze kuti awedzere gomba sulfate kurapwa, asi sarudza kuwedzera ferus sulfide. Mamwe makambani anosarudza kuwedzera simbi uye mhangura panguva imwe chete yekuburitsa kuchena kwakachena kusanzwisisika cyanide. Ferrous iron inokurumidza kutora okisijeni kubva kumhepo, inoshandura yakasviba yebhuruu, uye inofarira ferric ferricyanide.

Inogona kupedziswa kuburikidza nekuedza kuti yakanakisa yekubvisa cyanide kubva kuSolution neFerrous Sulfate ndeyekutsvaga maitiro ayo anogadzira shoma uye isingaoneki makomendi. Munguva yekuedza, takaverenga iyo molar chiyero cheiyo mhedzisiro yemugove wetsitsi uye cn-. Kutanga, iyo chiyero chakaverengerwa maererano naStoichiodometer yaive 0.39, asi iyo yakakwana molar chiyero chatawana kuburikidza nekuverenga yaive 0.5. . Iyo yakakwana pH yekunyepedzera prussian bhuruu ndeye 5.5 kusvika 6.5. Kazhinji, oksijeni inogona oxidize iron ions kuti iite Ferricyanide uye Ferrichyanide ions, iyo isinganyanye kusarangarira kwekubviswa kweCyanide. Nekuti Ferricyanate ion haina kugadzikana pasi pemamiriro ezvinhu emamiriro ezvinhu, ichaita kuti iite ferus pentacyano yakaoma. " ) 63-. Maitiro aya anoitika pane phengo yePH. is ph kukosha kwe5,5 kusvika 6.5. Iko kukosha kwenhamba ndiyo yakakodzera kwazvo, uye iyo chiyero che fe kuCN-0.5 ndiyo yakakodzera kwazvo kugadzirisa.
