Determination of Nitrate in Sea Water by Cadmium-copper Reduction to Nitrite*
An accurate, dependable determination of 0-60 ,ug-at./l. of NOs -N in sea water has been developed. The sample is treated with tetrasodium ethylenediaminetetraacetate solution and passed through a column of copperized cadmium filings. A nearly quantitative reduction of nitrate to nitrite results. Nitrite is then determined by a diazotization method. Neither sulphide nor high nitrite concentrati...
متن کاملConcentration of Nitrate in Bottled Drinking Water in Qom, Iran
Background & Aims of the Study: The global consumption of bottled water is growing with substantial growth in sales volumes on every continent. The highest growth rates are occurring in Asia and South America. Biological and chemical monitoring of these waters is necessary. The aim of current study was determination of nitrate concentration in bottled drinking water in Qom, Iran in 2012...
متن کاملSequential Injection Determination of Nitrate in Vegetables by Spectrophotometry with Inline Cadmium Reduction
A sequential injection system for the determination of nitrate (NO3 ) in vegetables was developed to automate this determination, allowing for substantially reduced reagent consumption and generated waste using low-cost equipment. After extraction with water and filtration, the extracted nitrate is reduced inline to nitrite in a copperized cadmium (Cd) column and determined as nitrite. Accordin...
متن کاملDetermination of inorganic nitrate in serum and urine by a kinetic cadmium-reduction method.
Nitrate in serum and urine was assayed by a modification of the cadmium-reduction method; the nitrite produced was determined by diazotization of sulfanilamide and coupling to naphthylethylene diamine. After samples were deproteinized with Somogyi reagent, the nitrate was reduced by Cu-coated Cd in glycine buffer at pH 9.7 (2.5 to 3 g of Cd granules for a 4-mL reaction mixture). The reduction f...
متن کاملThe conversion of nitrate in water to diatomic nitrogen gas by immobilized Pseudomonas stutzeri on vermiculite
Denitrification is a reduction of nitrate by heterotrophic and autotrophic bacteria that may ultimately produce molecular nitrogen (N2) through a series of intermediate nitrogen compounds.Vermiculite is a hydrous phyllosilicate mineral (Mg, Fe+2,Fe+3)3[(Al,Si)4O10](OH)2·4H2O with several layers for bacterial immobilization. The goal of this study was removal of nitrate from water with vermiculi...
