Abstract
A method for the determination of both the soluble and total sulphur in coal products has been devised. The procedure adopted for extracting the soluble sulphates from test materials was based on refluxing samples with hot, dilute HCl and H2O2, whereas the total sulphur content could be quantified after combustion with V2O5 in an O2 flow. The analytical determinations were accomplished by using inductively coupled plasma atomic emission spectrometry. The reproducibility (on average between 3.8 and 1.4%), linear dynamic range (4–5 orders of magnitude) and detection power (1 µg g–1 of sample) were found to be more than adequate for the stated purpose, thus providing a flexible and convenient tool for the determination of sulphur in coal and fly ash.Keywords
