Bibliography
This European standard specifies a Karl Fischer titrimetric method for the determination of the water content of fertilizers based on the use of 2-propanol as extracting medium.The method is applicable to all solid mineral fertilizers. The result (KFP water) includes "free" water and extracted water of crystallization from the following components of fertilizers: calcium nitrate tetrahydrate (Ca(NO3)2·4H2O); magnesium sulfate heptahydrate (MgSO4·7H2O); potassium chloride magnesium chloride hexahydrate (Carnallite, KCl·MgCl2·6H2O); magnesium nitrate hexahydrate (Mg(NO3)2·6H2O).
