Sets out a method for the determination of twelve elements in higher rank coal ash and coke ash by flame atomic absorption spectrometry after borate fusion. Methods for the determination of a further two elements are also referenced.
Scope
This Standard sets out a method for the determination of silicon, aluminium, iron, calcium, magnesium, sodium, potassium, titanium, manganese, barium, strontium and zinc in higher rank coal ash and coke ash by flame atomic absorption spectrometry after borate fusion. A spectrophotometric method for the determination of phosphorus and a method for the determination of sulfur are also referenced.
This method is suitable for the determination of the above elements (expressed as oxides), in the concentration ranges specified in Table 1.
