  • Chemical Denitrification of Nitrate from Groundwater Via Sulfamic Acid and Zinc Metal
    Iran. J. Environ. Health. Sci. Eng., 2006, Vol. 3, No. 3, pp. 141-146 CHEMICAL DENITRIFICATION OF NITRATE FROM GROUNDWATER VIA SULFAMIC ACID AND ZINC METAL *A. Sabzali, M. Gholami, A. R. Yazdanbakhsh, A. Khodadadi, B. Musavi, R. Mirzaee Department of Environmental Health, School of Public Health, Isfahan University of Medical Science, Isfahan, Iran Received 19 Jaunuary 2006; revised 5 March 2006; accepted 20 May 2006 ABSTRACT Nitrate contamination in drinking water can cause methemoglobinemia, which is especially detrimental to infants and nursing mothers. Batch experiments in two units for catalytic reduction of nitrate from groundwater with Zn catalyst and sulfamic acid were conducted. The system includes chemical denitriphication (ChemDen reactor) and electrolytic recovery reactoers. A batch study was conducted to optimize parameters like pH, sulfamic acid concentration, Zn concentration, temperature and reaction time governing the ChemDen process. The concentrations of remained nitrate and Zn were measured at the end of the reactions. Results showed that near to 100% of nitrate decreased and the quantity of remained nitrate was <1 mg/L. pH and agitation had great effect on denitrification, and the nitrate removal rate changed rapidly when pH value ranged between 3-4. Two water quality parameters which limit this process were sulfate and chloride ions concentrations in nitrate contaminated water. Key words: Chemical denitrification, groundwater, zinc, sulfamic acid, electrolytic reactor INTRODUCTION - Nitrate (NO3 ) concentrations in groundwater organic carbon is present. Water treatment have increased globally (Kapoor and Viraragh- processes stimulate denitrification by injection of avan 1997). Wastewater, fertilizers, and livestock nutrients. Such organic compounds as methanol, farming are major sources of nitrate in groundwater methane, glucose, and starch or mixtures of these supplies.

  • Reply to Dr. Wolfgang Wanek We Are Grateful for the Constructive Comments and Helpful Suggestions of Dr
    Reply to Dr. Wolfgang Wanek We are grateful for the constructive comments and helpful suggestions of Dr. Wanek. Below are detailed responses to all the comments and corresponding explanations of the revisions made to the manuscript. Line numbers cited in the replies (highlighted) refer to the revised manuscript document with tracked changes displayed (attached with this reply). Please refer to our replies to Referee #1 for other revisions of the manuscript. The paper reports on the isotopic fractionation of source and sink processes underlying soil NO emissions, NO emissions being important for atmospheric chemistry and as a soil N loss pathway. I am impressed by this study, proving in-depth analysis of isotopic constraints on formation and consumption pathways of soil NO, and partitioning the contribution of nitrifiers and denitrifiers as well as abiotic reactions. The approach taken with aerobic, suboxic and anoxic soil incubations combined with inorganic N additions in live and sterile soils, N and O isotope measurements in inorganic soil N and NO, amended by isotope fractionation and flux modeling provides a most complete assessment of NO source and sink processes. This study therefore highlights that stable isotope measurements in inorganic soil N with those in NO and N2O can help in source attribution of these important atmospheric gases. Reply: We are grateful for the encouraging remarks and positive feedback. Comment 1: Minor corrections can be found in the annotated PDF. Reply: We have incorporated all the corrections and edits into the revised manuscript. Thank you. Comment 2: Lines 59-61: There are also complete ammonia oxidizing Nitrospira, that catalyze the whole nitrification reaction sequence from ammonia to nitrate in one organism (comammox bacteria).
