Ethanol as a blending component for petrol - Determination of phosphorus content - Ammonium molybdate spectrometric method; English version of DIN EN 15487:2007-11
This standard specifies a procedure for the determination of phosphorus content measured as orthophosphate,
in ethanol from 0,15 mg/I to 1,50 mg/I by ammonium molybdate spectrometric method. The phosphorus
content is determined in aqueous solution after dissolution of the evaporation residue of the ethanol sample.
