A microwave digestion method for the determination of bromine in polyethylene (BCR 680 and 681) and peach leaves (SRM1547) by inductively coupled plasma mass spectrometry (ICP/MS) has been investigated. In the microwave digestion system, a sample of 0.1–0.3 g was weighed and 7 mL of nitric acid and 1 mL of hydrogen peroxide were added in a quartz insert. The insert was used within the standard TFM vessel which 6 mL of 10% hydrogen peroxide was added. The accuracy of the digestion method was evaluated. The recovery and the standard deviation (n = 3) for the bromine tested was 109% and 9.4%. The results obtained by the present method were in good agreement with the certified values.
