Removal of uranium(VI) by zero-valent iron (ZVI) has been suggested as a feasible pathway
to control uranium contaminations in seepage waters. Available information in literature
however presents discrepant evidence on the process responsible for the mitigation effect. On
basis of an EH-pH diagram of uranium and iron it is outlined that these discrepancies may be
explained by the aqueous chemistry of uranium and iron. Additional effects contributing to
the complexity of the system are given. Solubilization experiments using scrap iron together
with water works sludge, MnO2 and pyrite indicate that U(VI) is immobilized by iron
corrosion products after about 50 days.
