Multiple effects of nitrate amendment on the transport
From day 15 to 45 the obvious iron reduction in the presence of nitrate at day 45 was 30 days later than that in the control day 15 . Although the low ORP was favorable for iron reduction the inhibitory effect of nitrate on the bioreduction of Fe-Sb-bearing minerals could have resulted in the low mobilization of Sb in soils.
