Determination of Multi-elements in Airborne Dust with Air Filtrer Membrance Sampling

Airborne dust sample was collected with air filtrer membrance and then dissolved with mixed acid of HFHCl-HNO3-HClO4. 15 elements including Fe, Cu, Zn, Ni, La, Ce, Li, Mn, Cr, Cd, Co, Pb, Th, Tl, and U in the sample solution were determined by inductively coupled plasma-atomic emission spectrometry (ICP-AES) and inductively coupled plasmamass spectrometry (ICP-MS). The National Standard Reference Materials, simulated as airborne dust, were collected with air filtrer membrance and analyzed by ICP-AES and ICP-MS. The results were in agreement with the certified values with precision of less than 5%RSD (n=4) for all these elements.
