Process for desorption of ammonia chemical species using carbon dioxide, ammonia chemical species-providing agent, and apparatus for adsorption and desorption of ammonia chemical species

An adsorption and desorption apparatus of ammonia chemical species, comprising:

• a Prussian blue derivative holder adapted to receive and hold a Prussian blue derivative represented by the following general formula (1);
• an ammonia chemical species inlet adapted to introduce ammonia chemical species into the Prussian blue holder;
• a carbon dioxide inlet connected to a carbon dioxide cylinder adapted to introduce carbon dioxide into the Prussian blue derivative holder;
• a water inlet adapted to introduce water into the Prussian blue derivative holder;
• and
• an ammonia chemical species collector adapted to collect the ammonia chemical species from the Prussian blue derivative holder;
• AxM[M′(CN)6]y·zH2O (1)
• where x is 0 to 3, y is 0.1 to 1.5, z is 0 to 6, A is at least one cation of hydrogen, ammonium, an alkaline metal, and an alkaline earth metal, and M and M′ are each independently at least one cation of at least one of atoms having atomic numbers of 3 to 83 except for ammonium, an alkali metal, and an alkaline earth metal.
