Determination of total chromium in environmental water samples
Water Research, 2004 It is often desirable to quantify both dissolved Cr(VI) and total Cr in samples accurately. Various protocols are now being utilized to quantify the amount of total chromium in natural waters and each of these has possible interferences. This study describes the shortcomings of each method when particulate iron is present in a water sample, and a more ...

Proceedings of International Forestry and Environment Symposium, 2013 The two primary oxidation states of chromium in natural waters, Cr(Ill) and Cr(VI), differsignificantly in biological, geochemical and toxicological properties. Whereas Cr(Ill) isconsidered essential for human in glucose, lipid and protein metabolism, Cr(VI) is toxicbecause of its ability to oxidize other species and its adverse effects on the lung ...
