摘要：

Several methods utilizing microwave energy induced dissolution were developed for rapid digestion and subsequent analysis of automotive catalyst material by inductively coupled plasma mass spectrometry (ICP-MS). Dissolution was accomplished within 2-3 h rather than days as with the widely accepted ashing methods. A comparison was made with several other ICP-MS techniques and the conventional wavelength dispersive X-ray fluorescence method.
