Determination of trace elements in coal by atomic-absorption spectroscopy
Technical Report
·
OSTI ID:5457398
Methods based on atomic-absorption spectrophotometry, and involving various techniques for dissolution and measurement of the sample, have been developed for the determination of trace elements in coal. Non-volatile elements are determined by flame atomic absorption, and vanadium by electrothermal atomization of a solution, after ashing of the sample and dissolution of the residue with acid. Arsenic, selenium, bismuth, and tellurium are determined by hydride generation on a separate portion of the sample that has been ashed in the presence of sodium carbonate and fused with sodium peroxide. The laboratory methods are detailed in the appendices.
