title: A thermodynamic study of struvite+water system.
abstract: Equilibrium analysis of the system with MgNH(4)PO(4).6H(2)O (struvite) is taken as an interesting example of two-phase system where a change in solid phase composition (conversion) is affected by hydrolytic phenomena. The problem is presented in a comprehensive manner, based on results obtained from calculations made according to iterative computer program. The complex nature of phenomena occurred, with side effects resulting from presence of carbonate species, is explained. The analytical and physicochemical aspects of the matter are considered.
