Fertilizers--Determination of ammoniacal nitrogen content--Formaldehyde method
To make a sapphire crystal, the basic material used is a salt cleansed from any foreign body (ammoniacal alum).
cochineal, ammoniacal
Leaching of spent Li-ion battery in ammoniacal and H_2SO_4 solution
ammoniacal nitrogen [water quality objective]
Uses: Used in electroplating and producing other cobalt products, gas-pressure meter, densitometry and dry-wet indicator, also used as pigments in glass and ceramic industries, catalyst, drying agent in paint, ammoniacal absorbent and fodder additive, etc.
Fertilizers--Determination of ammoniacal nitrogen content--Titrimetric method after distillation
A yellow colour indicates the presence of ammoniacal nitrogen. Measure the transmittance of the solution by a spectrophotometer and compare the result with the standard curve.
