what is nh3-n/tkn?

Question

IT IS SOME TYPE OF CHEMICAL USED IN WATER TREATMENT

Answer 1

Definition for NH3-N
Ammonia Nitrogen - an inorganic, dissolved form of nitrogen that can be found in water, but in the presence of oxygen will convert to nitrate.

Ammonia (NH3-N)
an inorganic form of nitrogen, is contained in fertilizers, septic system effluent, and animal wastes. It is also a product of bacterial decomposition of organic matter. Ammonia NH3-N (NH3-N) becomes a concern if high levels of the un-ionized form are present. In this form NH3-N can be toxic to aquatic organisms. The presence of un-ionized ammonia is a function of the NH3-N concentration, pH, and temperature. Conversion of NH3-N to nitrite nitrogen by nitrification requires large quantities of oxygen which can kill aquatic organisms due to the lowered dissolved oxygen concentrations in water. NH3-N concentrations are reported in mg/L NH3-N.

Answer 2

It is actually a test to determine the amount of ammonia (NH3) in a sample expressed as Nitrogen. This is analyzed as a TKN (total kejdahl nitrogen)

Answer 5

We have carried out μSR experiments on [Co(NH3)6]Cl3 and [Co(ND3)6]Cl3. At 293 K, all the muons implanted into the complexes were in the diamagnetic state. The observed Gaussian-type muon spin relaxation function proved that the internal magnetic field was caused by nuclear dipole moments of the atoms in the complexes. In addition, another exponential-type muon spin relaxation function was observed in [Co(ND3)6]Cl3 below 50 K.
