Description

technical field [0001] The invention belongs to the field of liquid ammonia detection, in particular to an on-site fast, efficient and fully automatic detection system for liquid ammonia residues. Background technique [0002] Liquid ammonia, also known as anhydrous ammonia, is a colorless liquid with a strong pungent odor. As an important chemical raw material, ammonia is widely used. In order to facilitate transportation and storage, gaseous ammonia gas is usually pressurized or cooled to obtain liquid ammonia. Liquid ammonia is easily soluble in water and forms ammonium ion NH after dissolving in water 4 + and hydroxide ion OH - , making the solution alkaline. Liquid ammonia is mainly used to produce nitric acid, urea and other chemical fertilizers, and can also be used as a raw material for the production of medicines and pesticides. Liquid ammonia can also be used in the national defense industry as a propellant for rockets and missiles, as well as an ammonificatio...
