Inhibition of bacterially promoted uranium reduction: Ferric (hydr)oxides as competitive electron acceptors.
Journal Article

· Environmental Science and Technology
Reduction of hexavalent to tetravalent uranium results in a marked decrease in the mobility of this hazardous element. Microbial reduction is the most kinetic viable mechanism for such a reaction. Unfortunately, alternate terminal electron acceptors may thus compete with uranyl. We examine the role of common iron oxides on uranyl reduction. Only poorly ordered iron oxides altered the degree and rate of hexavalent uranium reduction and the effect was transitory.
