ABSTRACT
Chromium is a rather ubiquitous element in both the natural environment and in our everyday surroundings. Chromium can be found in various oxidation states with trivalent chromium, Cr(III), being an essential micro-nutrient, and hexavalent chromium, Cr(VI), being a known carcinogen. The need to quantitatively differentiate between these two valence states is a hot topic in the environmental and academic communities as regulations seek to drive the acceptable limits for the toxic, hexavalent form lower as a matter of public health. In this work, we will discuss a low-level quantitative method for the accurate determinations of these chromium species at the sub-part-per-billion range.
