To evaluate the effectiveness of sodium bicarbonate (SB) in removing uranium and protecting animals from uranium toxicity, we intramuscularly administered 1 mg/kg of uranyl nitrate to 8-wk-old male SD rats, and 20 min after administration of uranyl nitrate, the animals were given a single oral administration of SB at 0.1, 0.3 or 1 g/kg. The SB treatment at a dose of 0.3 g/kg or more raised the ...

A rapid and sensitive spectrophotometric method for the determination of nitrate in vegetables is described. The method is based on the measurement of the absorbance of yellow sodium nitrophenoxide formed via the reaction of phenol with the vegetable-based nitrate in presence of sulphuric acid. The analytical concentration of the acid has marked effect on the nitrate determined. The colour deve...

Dox medium which contains 1.0 g. NaNO3/l. (0.1 %). As the nitrate concentration is further increased, the growth, indicated by the mycelium yield and the production of solerotiose, is progressively reduced. While Fig. 1 indicates that maximum KCl consumption is obtained on media of low nitrate content, Fig. 2 shows a parallelism of sclerotiorine production with growth, in nitrate concentrations...

Minimum inhibitory concentration of carbendazim among the 12 isolates Alternaria dauci (Kuhn) Groves & Skollo causing leaf blight carrot showed variation. Isolate Ad-11 was most sensitive have MIC 6% and Ad-2 highly resistant 20%. The effect Ammonium nitrate, Calcium Sodium nitrate Zinc were tested growth rate carrot. found to be best source nitrogen for both isolates.

This paper describes azidation of indoles with NaN3 and ceric ammonium nitrate (CAN), giving a variety of spirocyclic 2-azido indolines in good yields and moderate diastereoselectivities.

The existing evidence for the nature of the phase diagram for the binary system sodium nitrate-potassium nitrate is reviewed and in particular whether the system is of the continuous solid solution type, as has often been stated in the last 80 years, or whether this system is of the eutectic type as was earlier believed and has again been asserted recently. Additional evidence from Raman spectr...

A family outbreak of methaemoglobinaemia following ingestion of sausages made using 'saltpetre' is reported. Saltpetre is a generic term for several potassium and sodium based compounds. On this occasion imprecise ordering led to the use of sodium nitrite rather than the usual potassium nitrate, with extremely serious consequences.

5,5-Dimethylpyrroline N-oxide (15N) and 5,5-di(trideuteromethyl)pyrroline N-oxide were synthesized from the respective isotopically labeled 2-nitropropane analogs obtained from the reaction of sodium nitrate with 2-halopropanes. This facile, straightforward process allows synthesizing isotopically labeled DMPO analogs in a 4-step reaction without special equipment.

Groundwater pollution by nitrate is a worldwide problem. To evaluate the performance of fuzzy regression method and support vector machines (SVM) for estimating the nitrate concentration, an analysis was conducted. In this research, 175 observation wells in Isfahan province, Iran, were selected and the concentration of nitrate, potassium, magnesium, sodium, chlorine, bicarbonate, sulphate, calc...
