Trivalent Chromium vs. Hexavalent Chromium

1. Litšobotsi tsa Lik'hemik'hale:

• Trivalent Chromium (Kr(III)):
  • Tlhaho: E etsahalang ka tlhaho, ka kakaretso e nkoa e le chefo e nyane.
  • Boemo ba Oxidation: Chromium e teng ka har'a +3 boemo ba oxidation.
• Hexavalent Chromium (Kr(VI)):
  • Tlhaho: Hangata ke sehlahisoa sa indasteri, e tsebahalang ka chefo e phahameng.
  • Boemo ba Oxidation: Chromium e teng ka har'a +6 boemo ba oxidation.

2. Phello ea Bophelo bo Botle le Tikoloho:

• Trivalent Chromium:
  • Tšusumetso ea Bophelo bo Botle: Ka kakaretso e nkoa e se kotsi ho bophelo bo botle ba batho.
  • Tšusumetso ea Tikoloho: E beha likotsi tse tlase tsa tikoloho.
• Hexavalent Chromium:
  • Tšusumetso ea Bophelo bo Botle: E tsebahala ka chefo e phahameng, e amanang le phefumoloho le mathata a letlalo.
  • Tšusumetso ea Tikoloho: E kotsi ho feta, mme e baka dikotsi tse kgolo ho tikoloho.

3. Tšebeliso ea Liindasteri le Lisebelisoa:

• Trivalent Chromium:
  • Lisebelisoa: Hangata e sebelisoa ka ho khabisa chrome plating, dithulaganyo tsa go suga matlalo, le liaparo tse ling tse thibelang ho bola.
• Hexavalent Chromium:
  • Lisebelisoa: E sebelisitsoe ka nalane lits'ebetsong tse fapaneng tsa indasteri, ho kenyelletsa le plating ea chrome, empa tšebeliso ea eona e thibetsoe ka lebaka la mathata a tikoloho le bophelo bo botle.

4. Melemo le Mefokolo:

• Trivalent Chromium:
  • Melemo: Ka kakaretso e nkoa e sireletsehile, le ho feta tikolohong.
  • Mefokolo: E kanna ea ba le mefokolo lits'ebetsong tse ling tsa indasteri ka lebaka la ho hanyetsa kutu ho tlase ha ho bapisoa le chromium e hexavalent..
• Hexavalent Chromium:
  • Melemo: E ne e nkoa e le ea bohlokoa historing bakeng sa khanyetso ea eona e phahameng ea ho senya lits'ebetsong tsa indasteri.
  • Mefokolo: Chefo e phahameng, melao e thata e thibelang tšebeliso ea eona, le dingongoreho tsa tikoloho.

5. Bothata ba Tlhahiso le Litšenyehelo:

• Trivalent Chromium:
  • Bothata ba Tlhahiso: Tsoelo-pele ea theknoloji e ntlafalitse mokhoa oa tlhahiso, ho etsa hore trivalent chromium e fumanehe haholoanyane.
  • Litšenyehelo: Ka kakaretso, theko ea tlhahiso ea trivalent chromium ke ea tlholisano.
• Hexavalent Chromium:
  • Bothata ba Tlhahiso: Ho ea ka nalane ho bonolo ho hlahisa, empa melao e thata haholoanyane e ekelitse bothata.
  • Litšenyehelo: Ho latela melao ea tikoloho le mehato ea polokeho ho ekelitse litšenyehelo tsa tlhahiso.

6. Tikoloho ea Taolo:

• Trivalent Chromium:
  • Boemo ba Taolo: Ka kakaretso ho amoheloa ho feta le ho fokolloa ke taolo ka lebaka la chefo e tlase.
• Hexavalent Chromium:
  • Boemo ba Taolo: E laoloa haholo ka lebaka la mathata a bophelo bo botle le tikoloho. Libaka tse ngata li beha meeli e thata tšebelisong ea eona.

Ha re phethela, khetho pakeng tsa trivalent le hexavalent chromium e itšetlehile ka ts'ebeliso e khethehileng, ho latela melao, le maikutlo a tikoloho. Le ha trivalent chromium ka kakaretso e nkuoa e le khetho e sireletsehileng, ka bobeli li na le melemo le mefokolo ea tsona, mme indasteri e ntse e tswela pele ho tswelapele ho ya mekgweng e tsitsitseng le e baballang tikoloho.
