nitrate

 [ni´trāt]
any salt or ester of nitric acid; organic nitrates are used in the treatment of angina pectoris and as preservatives in meat products. Some individuals have sensitivity to nitrates and may suffer from headache, diarrhea, or urticaria after ingesting them.

(2) The characteristics (SEM and EDAX, surface area, pore structure, zeta potential, Raman spectra, and FTIR) indicated that the mechanism of nitrate adsorption mostly depended on the electrostatic attraction between the free nitrate ions and the positively charged ions, almost without any chemical interactions.
From the result that is obtained, nitrate ion concentration in the study area ranges from 1.20 mg/l to 9.60 mg/l.
The effects of light intensity, nitrate ions, chloride ions, humic acid, and pH on the photochemical degradation of TCNM were investigated under the irradiation of low pressure mercury lamp ([lambda] = 254nm, 12 W).
split nitrogen application, utilisation of slow release fertilisers, and incorporation of soil amendments that increase ammonium and nitrate ion retention.
The nitrate ion, by contrast, moves freely in the soil because of its negative charge.
However, further studies with Emmenanthe penduliflora found that the nitrate ion alone failed to induce germination (Keeley and Fotheringham 1998), rather nitrogen oxides were the compounds responsible for smoke-stimulated germination (Keeley and Fotheringham 1997).
The nitrogen atom in the nitrate ion is electron deficient and needs to accept electrons to relieve bonding stress.
Ammonium ion removal was expected to reduce microbially mediated nitrification, thereby reducing the formation of nitrite and nitrate ion during distribution.
Attached to each one of the active sites is a chloride ion, but as the nitrate ion comes through, it has such a strong affinity to the site that it bumps the chloride off and attaches itself, said McMullen.
The unidentate and bidentate nitrates show the frequency separation of 115 and 186 cm-1 respectively while the combination bands (1+4) for free nitrate ion appear in the regions of 1800-1700 cm-1 [3031].
The [D.sub.3h] symmetry of the free nitrate ion is lowered to [C.sub.2v] on complex formation and six normal modes are expected to be IR active [32].
