Study on Impact Factors of Reducing U(VI) by S. oneidensis

Abstract:

Impact Factors of reducing U(VI) by the Shewanella oneidensis Were studied in this study. The results showed S. oneidensis has highly resistant to acid and Uranium. U(VI) initial concentration has the very big influence on reduction of U(VI) and the optimum U(VI) concentration is 30mg/Lwith removal rate of 95.02% at 4 days, Metal ions Cu2+,Mn2+ and Ca2+ impact on the reduction of U(VI). equal concentrations of Cu2+ and Mn2+ could cause varying degrees of inhibition of U(VI) reduction, Ca2+ acted as a weak role in promoting the reduction, the coexisting ions of SO42-and low concentration of no3-(<0.5mmol/L) did not markedly influence the reduction efficiency of U(VI). zero alent iron (ZVI) can accelerate the reduction of U(VI) by the S. oneidensis .
