Nitrate reduction by iron supported bimetallic catalyst in low and high nitrogen regimes
Hamid, Shanawar; Lee, Woojin;
 Abstract
In this study, the effect of initial nitrate loading on nitrate removal and byproduct selectivity was evaluated in a continuous system. Nitrate removal decreased from 100% to 25% with the increase in nitrate loading from 10 to . Ammonium selectivity decreased and nitrite selectivity increased, while nitrogen selectivity showed a peak shape in the same range of nitrate loading. The nitrate removal was enhanced at low catalyst to nitrate ratios and 100% nitrate removal was achieved at catalyst to nitrate ratio of . Maximum nitrogen selectivity (47%) was observed at , showing that continuous Cu-Pd-NZVI system has a maximum removal capacity of 37 mg . The results from this study emphasize that nitrate reduction in a bimetallic catalytic system could be sensitive to changes in optimized regimes.
