空气滤膜采集大气浮尘样品中多元素的测定

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

摘要: 用氢氟酸-盐酸-硝酸-高氯酸体系对空气滤膜上附着的浮尘样品进行分解，电感耦合等离子体发射光谱法、电感耦合等离子体质谱法同时测定溶液中15个主量和微量元素铁、铜、锌、镍、镧、铈、锂、锰、铬、镉、钴、铅、钍、铊、铀。将国家一级标准物质模拟浮尘样品加入空白滤膜进行测定，结果与标准值相符。各元素4次测定结果的相对标准偏差（RSD）小于5%。

Abstract: 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.
