- I-Hexavalent Chromium (Cr(VI)):
- Imvelo: Ngokuvamile umkhiqizo wemboni, eyaziwa ngobuthi obuphezulu.
- Isimo se-Oxidation: I-Chromium ikhona ku- +6 isimo se-oxidation.
2. Umthelela Wezempilo Nezemvelo:
- I-Trivalent Chromium:
- Umthelela Wezempilo: Ngokuvamile kubhekwa njengengozi encane empilweni yomuntu.
- Umthelela Wezemvelo: Idala ubungozi obuphansi bemvelo.
- I-Hexavalent Chromium:
- Umthelela Wezempilo: Kwaziwa ngobuthi obuphezulu, ezihambisana nezinkinga zokuphefumula nesikhumba.
- Umthelela Wezemvelo: Okuyingozi kakhulu, futhi kubangela ubungozi obukhulu kuma-ecosystem.
3. Ukusetshenziswa Kwezimboni Nezicelo:
- I-Trivalent Chromium:
- Izinhlelo zokusebenza: Okuvame ukusetshenziswa ekuhlobiseni i-chrome plating, izinqubo zokushuka, kanye nezinye izigqoko ezilwa nokugqwala.
- I-Hexavalent Chromium:
- Izinhlelo zokusebenza: Ngokomlando yayisetshenziswa ezinqubweni ezihlukahlukene zezimboni, kufaka phakathi i-chrome plating, kodwa ukusetshenziswa kwayo kukhawulelwe ngenxa yokukhathazeka kwemvelo nempilo.
4. Izinzuzo nobubi:
- I-Trivalent Chromium:
- Izinzuzo: Ngokuvamile kubhekwa njengokuphephile, futhi enobungani nemvelo.
- Okubi: Ingase ibe nemikhawulo kwezinye izinhlelo zokusebenza zezimboni ngenxa yokumelana nokugqwala okuphansi uma kuqhathaniswa ne-hexavalent chromium.
- I-Hexavalent Chromium:
- Izinzuzo: Ngokomlando yaziswa ngenxa yokumelana kwayo nokugqwala okuphakeme ezinqubweni zezimboni.
- Okubi: Ubuthi obuphezulu, imithetho eqinile ekhawulela ukusetshenziswa kwayo, kanye nokukhathazeka kwemvelo.
5. Ubunzima bokukhiqiza kanye nezindleko:
- I-Trivalent Chromium:
- Ubunzima bokukhiqiza: Intuthuko kwezobuchwepheshe ithuthukise inqubo yokukhiqiza, okwenza i-chromium eyi-trivalent ifinyeleleke kakhudlwana.
- Izindleko: Ngokuvamile, izindleko zokukhiqiza ze-trivalent chromium ziyaqhudelana.
- I-Hexavalent Chromium:
- Ubunzima bokukhiqiza: Ngokomlando kulula ukukhiqiza, kodwa imithetho eqinile iye yandisa ubunzima.
- Izindleko: Ukuhambisana nemithethonqubo yezemvelo kanye nezinyathelo zokuphepha kwenyuse izindleko zokukhiqiza.
6. Imvelo Elawulayo:
- I-Trivalent Chromium:
- Isimo Sokulawula: Ngokuvamile kwamukeleka kakhulu futhi akulawulwa kancane ngenxa yobuthi obuphansi.
- I-Hexavalent Chromium:
- Isimo Sokulawula: Ilawulwa kakhulu ngenxa yokukhathazeka kwezempilo kanye nemvelo. Izifunda eziningi zibeka imingcele eqinile ekusetshenzisweni kwayo.
Ekuphetheni, ukukhetha phakathi kwe-chromium eyi-trivalent ne-hexavalent kuncike kuhlelo lokusebenza oluthile, ukuhambisana nokulawula, nokucatshangelwa kwemvelo. Ngenkathi i-chromium eyi-trivalent ngokuvamile ithathwa njengenye indlela ephephile, zombili zinezinzuzo kanye nokulinganiselwa kwazo, futhi imboni iyaqhubeka nokuguqukela ezenzweni ezisimeme nezingangeni kwemvelo.
