- W2242803803 abstract "Background: Today, global concerns about nitrate in groundwater and its adverse impact on health have increased. This study aimed to evaluate the efficiency of Nitrate reduction by Fe/H2O2 process and adsorption on the activated carbon. Materials and Methods: In this experimental-laboratory study, Nitrate oxidation by the advanced oxidation process Fe°/FeІІ/FeШ/H2O2 at pH 2-10, contact time 10-90 min, Nitrate concentrations of 50-300 mg/L was considered. A spectrophotometer was used to measure Nitrate in the effluent. Results: Results showed that the optimal parameters in the Fenton process in order to remove nitrate include: pH 3 and the contact time 15 min. By applying these conditions, the Nitrate removal efficiency in the retention time (90 min), initial nitrate concentration in 100 mg/L, iron concentration 10 mg/L and pH 4 for FeШ، FeІІ، Fe°، FeІІ/Fe°/H2O2 and FeШ/Fe°/H2O2 were 10.5%, 27.6%, 36.5%, 62.3% and 74%, respectively. Conclusion: According to the results, it was determined that the corrective fenton process with zero iron nano-particles can effectively reduce Nitrate under optimal conditions and this method can be used for the removal of similar compounds. Moreover, it was determined that the use of iron compounds in the presence of hydrogen peroxide can have a desirable effect on the decomposition of Nitrate and this method can be used for the removal of similar compounds." @default.
