Microwave-assisted acid digestion (MW-AD) followed by atomic spectrometry such as ICP-MS was examined for the determination of trace elements in coal and coal fly ash. For coal, the addition of HF in the acid mixture of MW-AD was not needed for the recovery of trace elements. For coal fly ash, the optimum conditions for the addition of HF was examined, and it was proved that the conditions established were effective for various samples.
