| http://www.w3.org/ns/prov#value | - While nitrate was reduced mostly to ammonium when Cd(II) was not present or at Cd(II) concentrations???????40???mg/L, up to 20% of the initial nitrate was reduced to nitrite at Cd(II) concentrations???<???40???mg/L. Among nZVI particles doped with 1???wt. % Cu, Ag, or Au, nZVI deposited with 1???wt. % Au reduced nitrite yield to less than 3% of the initial nitrate, while maintaining a high Cd(II)
