Waa maxay Doorka Sodium Metabisulfite ee Daaweynta Biyaha Wastada Warshadaha

1. Sodium metabisulfite waa wakiil wax-yareeya, kaas oo loo isticmaalo in lagu daweeyo biyaha wasakhda ah ee chromium-ka ku jira ee daaweynta wasakhda.
2. Biyaha wasakhda ah ee Chromium ku jira waa in si gooni ah loola dhaqmo si waafaqsan heerarka qaranka, lagumana sii dayn karo barkada isku dhafan iyo xoojinta chromium-ka hexavalent waa in aanu ka sarrayn 0.1
3. Sidaa darteed, meesha ay ku dhacayso sodium metabisulfite waxay ku jirtaa biyaha ceeriin ee chromium-ka ku jira wasakhda si loo yareeyo chromium hexavalent ilaa chromium trivalent ka dibna uu soo da'o.
