ResumoTrace elements in energy-relatd materials (coal, residual fuel oil, and shale oil) are quantified by inductively-coupled plasma atomic emission spectrometry after separation and preconcentration with a poly(dithiocarbamate) chelating resin. Trace elements were determined in coal (NBS 1632a), in a residual fuel oil (NBS 1634a), and in a shale oil (TOSCO). Detection limits ranged from a low of 2 ng ml−1 for manganese to a high of 150 ng ml−1 for lead. Relative standard deviations ranged from 1 to 5% and deviations from certified values (coal and residual fuel oil) were in the same range for fourteen elements. Recoveries of 1–5 μg of twelve elements added to the shale oil ranged from 96 to 99.5%.
