実験手順
The monocalcium phosphate solid was then reacted with a stoichiometric amount of potassium sulfate in aqueous solution to form KH2PO4 and calcium sulfate. The calcium sulfate precipitate is separated by filtration and recovered. The solution or filtrate from this filtration is subjected to evaporation for the precipitation of potassium dihydrogen phosphate which is then recovered by filtration.
