Fertilizers - Determination of water content (Karl Fischer methods) - Part 2: 2-propanol as extracting medium
Preview
Summary
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).
