5 October 2007 ISSN 1816-7950 = Water SA (on-line) 615 Abiotic reduction mechanism of As(V) by fulvic acid in the absence of light and the effect of Fe(III) Tsanangurayi Tongesayi1* and Ronald B Smart 2 1 Monmouth University, Department of Chemistry, Medical Technology and Physics, 400 Cedar Avenue, West Long Branch, NJ 07764 2 West Virginia University, Department of Chemistry, PO Box 6045, Morgantown, WV 26506-6045 Abstract In this paper, the mechanism of the redox cycling of arsenic under dark conditions was studied to help explain the high prevalence of As(III) in groundwater where no photochemical redox cycling is expected to occur.
