Sets out a method for the spectrophotometric determination of phosphorus in coal by a borate fusion/molybdenum blue method using a rapid ashing technique. This method does not involve the use of hydrofluoric acid.
Scope
This Standard sets out a method for the spectrophotometric determination of phosphorus in coal by a borate fusion/molybdenum blue method using a rapid ashing technique. The method is rapid and does not involve the use of hydrofluoric acid.
An alternative method is also given for determination of phosphorus in coal, ashed in accordance with AS 1038.3. This method can be used if a very rapid turnaround time is not required, or if ash has already been prepared for analysis.
