Chromium(VI) is a known carcinogen that is very difficult to remove from groundwater. One potential method of remediation of chromium(VI)-contaminated groundwater involves using iron nanoparticles. Iron can reduce chromium(VI) to chromium(III) which is less toxic and is easier to remove from groundwater. Bench-top experiments using micro- and nano-scale iron particles have been performed on well-characterized solutions in order to determine the kinetics of the reaction and in order to determine the conditions under which the reaction is most effective. The studies have involved varying the pH of the solution and the size of the iron particles. Experimental details and the results of these experiments are the subjects of this presentation.
