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%。
Airborne dust sample was collected with air fihrer 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.
