WebJun 1, 1997 · Abstract. To better understand the geochernical processes that result in the reduction of hexavalent chromium [Cr (VI)] in natural waters, the reaction of Cr (VI) with Fe (II) has been studied as a function of pH and temperature. Over the concentration range studied [0.3–100 μM Fe (II) and 0.9–600 μM Cr (VI)], the reaction follows first ...
