Ammonium nitrate total oxygen

The data set treated in this study is a part of the above-mentioned measurements in the Struma River basin. The period of observation in this region was 10 years (1989-98), and the chemical indicators were pH, dissolved oxygen, BOD5, COD, conductivity, acidity, DISS, N-DISS, total hardness, chloride, sulfate, ammonium, nitrate, nitrite, iron, magnesium, and calcium. 

Ammonium nitrate is the most important raw material in the manufacture of industrial explosives. It also serves as a totally gasifiable oxygen carrier in rocket propellants. 

The pilot plant was started daily during the 113 days of the experimentation. Samples were taken from the permeate stream, from the bioreactor, and from the water reaching the bioreactor after the physical-chemical treatment. A series of daily, weekly, and monthly analyses were carried out on these samples. The daUy analyses included pH, conductivity, temperature, dissolved oxygen in the reactor, COD, and permeate turbidity. The weekly analyses included BOD5, suspended sohds, volatile sohds, ashes, ammonium, nitrates, nitrites, total nitrogen, and total ortho phosphoms. The monthly analyses included sulfides, total chromium, and salts, all referred to as sodium chloride. 

Nitrated" Gun-Cotton.—The nitrates that are or have been mixed with gun-cotton in order to supply oxygen are potassium nitrate, ammonium nitrate, and barium nitrate (tonite). The total combustion of gun-cotton by potassium nitrate corresponds to the equation --... 

If reservoir rock temperature in the zone is to be raised by 200 K, then 3.125x105 GJ of heat must be added. Since approximately 5 GJ of heat is generated per tonne of ammonium nitrate decomposed, the required amount of nitrate is 6.25 x 104 toimes. The total mass of the gas produced by decomposition (nitrogen, oxygen, and water vapor) is equal to the mass of ammonium nitrate consiuned. Therefore, 0.5 t of gas must be released to heat one tonne of reservoir oil. This is srrfircient to expect a rapid increase in well production rate even at an early stage of ammonium-nitrate injection into the reservoir. 

NO negative effect of DLG on nitrate-dependent oxygen evolution was, however, observed in Anacystis cells in i ich ammonium assimilation had been inhibited by treatment with the glutamine synthetase inactivator, MSX. The results in Table 1 show that MSX-treated cells subjected to the action of DLG exhibit rates of nitrate-dependent oxygen evolution analogous to control cells (either untreated or treated with MSX) in spite of the total inhibition of the CX)2 dependent oxygen evolution caused by DLG. These observations support those of Stokes and Walker (1972) regarding the action of DLG as a pure "dark" inhibitor of OO2...

Photolytic. Low et al. (1991) reported that the photooxidation of a saturated solution of atrazine by UV light in the presence of titanium dioxide resulted in the formation of ammonium, carbonate, chloride, and nitrate ions. Evgenidou and Fytianos (2002) also studied the photodegradation of atrazine using UV light (X >290 nm) in distilled water (pH 7.1, conductivity 456 mS/cm, dissolved oxygen 8.0 mg/L, total organic carbon 0.8 mg/L), lake water (pH 8.7,...

In order to characterize water quality, the following parameters were measured from the water samples in accordance with Hungarian Standards total organic carbon (TOC), chemical oxygen demand, concentrations of ammonium, nitrite and nitrate ion, iron, manganese, pH, conductivity, m-alkality, turbidity, and heterotroph colony count.
