Ammonium magnesium phosphate hexahydrate is a compound that has been used in the treatment of wastewater and as an adsorbent for air emissions. It is also used to inhibit bacterial growth due to its potent antibacterial activity. Ammonium magnesium phosphate hexahydrate is a white powder with a molecular weight of 288.3 grams per mole. It has a strong adsorption capacity and can be used to treat urinary infections in women. The inhibition study revealed that the reaction products are mainly composed of ammonium ions, magnesium ions, and phosphates. The activation energies for this reaction are high, which may be due to the relatively high affinity between ammonium ions and water molecules. The morphology of this compound is crystalline or granular in nature with some amorphous regions present on the surface.
