Abstract
Fast and efficient sample digestion is achieved by a microwave-nitric acid procedure. The ICP-MS analysis is performed with single standard calibration. The optimum condition of microwave digestion is determined. Dried samples of 0.1g were digested into the Teflon cup of high-pressure microwave acid-digestion bomb for 20-30 seconds. For all elements except Ca and Cu, good agreement exists between ICP -MS and certified values
