Solid mineral fuels. Determination of phosphorus content. Reduced molybdophosphate photometric method Ingestion-build-103253 It sets an international benchmark1 Scope This document specifies a reduced molybdophosphate photometric method for the determination of the total phosphorus content of hard coal, lignites and coke. Two methods for taking the phosphorus into solution are specified, namely extraction from the coal or coke ash with acid or by repeated oxidation of the coal or coke, by acid, to remove carbonaceous matter.
