Umhlinzeki we-Potassium Permanganate eNingizimu Afrika

I-ejenti enamandla yokuxosha insimbi, i-manganese, kanye ne-hydrogen sulfide emanzini okuphuza — i-potassium permanganate iyi-oxidant ejwayelekile yegolide yokwelashwa kwensimbi kanye ne-manganese emanzini angaphansi komhlaba ezinhlelweni zokuphakelwa kwamanzi zikamasipala nezangasese.

Iyini i-Potassium Permanganate?

I-Potassium permanganate (KMnO₄) iyi-ejenti enamandla ye-inorganic oxidising ebonakala njenge-granules ezinsomi ezimnyama kuya kwezimnyama futhi yakha isisombululo esinombala onsomi ocacile emanzini. Ekuphathweni kwamanzi, i-KMnO₄ ingenye yama-pre-oxidants abaluleke kakhulu asetshenziswa ukususa insimbi encibilikisiwe (Fe²⁺), i-manganese (Mn²⁺), kanye ne-hydrogen sulfide (H₂S) emithonjeni yamanzi angaphansi komhlaba. Lokhu kungcola kubangela ukunambitheka, iphunga, umbala, kanye nezinkinga zokufaka amabala emanzini okuphuza futhi kumele kususwe ngaphambi kokusatshalaliswa. I-KMnO₄ i-oxidizes i-Fe²⁺ kanye ne-Mn²⁺ ibe yi-Fe³⁺ kanye ne-MnO₂ enganyibiliki, bese isuswa ngokuhlunga noma ukuthungwa.

Ukususwa kwe-Iron ne-Manganese Emanzini Angaphansi Komhlaba

Ekuhlanzweni kwamanzi emigodini kamasipala nangasese, i-potassium permanganate ifakwa emanzini angavuthiwe ngaphambi kwesihlungi sokwelapha ukuze kufakwe i-oxidize iron encibilikayo kanye ne-manganese. Ukusabela: 2KMnO₄ + 3Fe²⁺ + 7H₂O → 2MnO₂ + 3Fe(OH)₃ + 2K⁺ + 4H⁺ ikhiqiza i-MnO₂ engancibiliki kanye ne-iron(III) hydroxide ebanjwa embhedeni wesihlungi. I-MnO₂ ekhiqizwayo iphinde ivuselele i-oxidation ye-Mn²⁺ futhi isebenze njenge-oxidizing filter media (izinhlelo zesihlungi se-greensand). I-H₂S, ebangela izinkinga zephunga emanzini angaphansi komhlaba, i-oxidized ibe yi-elemental sulfur noma i-sulfate engenaphunga yi-KMnO₄, isuse iphunga "leqanda elibolile" emanzini athintekile.

Ezinye Izicelo Zokwelashwa Kwamanzi Nezimboni

I-KMnO₄ isetshenziswa ezinhlelweni zamanzi ahlanzekile ukulawula amakhemikhali abangelwa ulwelwe abangela ukunambitheka nephunga (i-geosmin, i-MIB) ngokuwohloka kwe-oxidative. Isetshenziswa ekwelapheni amanzi angcolile ukuze i-oxidative phenols, i-cyanides, kanye nokungcola okungokwemvelo. Embonini yezimayini, yelapha ukugeleza kwe-acid mine ngokufaka i-oxidation ku-ferrous iron, futhi isetshenziswa ekususeni i-cyanide emanzini angcolile okumbiwa kwegolide. I-Terracore Chemicals inikeza i-potassium permanganate ezikhwameni ezingama-25 kg kanye nasezikhwameni ze-1 MT kulo lonke elaseNingizimu Afrika.

Izicelo

Ukususwa kwensimbi kanye ne-manganese emanzini angaphansi komhlaba kanye nokususwa kwayo
Ukususwa kwephunga lamaqanda abolile ngamanzi emigodini H₂S (iphunga lamaqanda abolile)
Ukuhlanza amanzi kamasipala ngaphambi kokuhlanza
Ukulawulwa kokunambitha nephunga (i-geosmin, i-MIB) emanzini angaphezulu
Ukukhishwa kwensimbi kanye nokwelashwa kokukhipha amanzi emayini ye-asidi
Ukubhujiswa/ukususwa kwe-cyanide emanzini angcolile okumbiwa (oxidative)
Ukwelashwa kwamanzi amdaka ezimbonini — i-phenol kanye ne-organic oxidation
