ABOUT CHROMIUM VI
Hexavalent chromium (chromium VI) is a common form of chromium, a metallic element, that can exist in natural waters in concentrations ranging from 1 to 100 ug/L.
ABOUT CHROMIUM VI
Chromium VI is an important water quality parameter to monitor in drinking water as it is a known carcinogen for humans. Chromium VI is released in small amounts from rocks and soils, however it can also be released from anthropogenic sources such as industrial pollution. The EPA currently has a maximum contaminant level (MCL) for total chromium species (Cr(III) plus Cr(VI)) of 100 µg/L (0.1 mg/L).
ABOUT CHROMIUM VI
A common method for chromium VI measurement is Method 218.7. A known volume of sample is introduced into an ion chromatograph. The chromate ion is separated from other matrix components on an anion exchange column. It is then derivatized and detected spectrophotometrically at 530 nm. The concentration is calculated and results are reported in units of µg/L of chromium VI.
