NITRATE, a common and serious contaminant of ground water, is removed at present either by physicochemical methods that do not degrade it, or via degradation by microorganisms, which is a slow process1. We report here a rapid and efficient process for nitrate removal which involves catalytic redu...
Nitrate and nitrite levels in our natural water supplies are important indicators of water quality. The increasing levels of nitrate and nitrite concentrations are becoming an important problem for public health. Nitrates are of great toxicological concern as they are involved in the origin of nitrite...

作者: National Research Council (US) Subcommittee on Nitrate and Nitrite in Drinking Water 摘要: The World Health Organization (WHO) guideline of 50 ppm and the US maximum contaminant level (MCL) of 45 ppm for nitrate in drinking water are established for the protection of infants from met...
analysis showed a negative correlation between Nitrite concentrations anddepth of the aquifer (P-value = 0.034, R = 0.44), ie, with increasing depth there werelower nitrate levels.There was no relationship between nitrate concentrations and the distance of water wellsfrom the sites of wastewater ...

nitrate in newborn infants Jesica A. Jones1, Andrew O. Hopper1, Gordon G. Power2 and Arlin B. Blood1,2 Nitrate and nitrite are commonly thought of as inert end prod- ucts of nitric oxide (NO) oxidation, possibly carcinogenic food additives, or well-water contaminants. ...
An improved rapid method of extraction-photometric determination of trace amounts of nitrate and nitrite in water has been developed. In this method, nitrate is quickly reduced to nitrite at pH 3.0 in 5 min with freshly prepared cadmium sponge, which is produced in situ by action of zinc ...
