1. Introduction. Chromium (Cr) is an element that belongs to the heavy metals group. Its oxidation state ranges from -2 to +6, however, it is found in nature at its more stable forms: trivalent chromium (CrIII) and hexavalent chromium (CrVI) [1].CrIII plays an important nutritional role, although its mechanisms are not fully understood.
