单标法中子活化分析对标准参考物质——煤飞灰的测定

MULTIELEMENT DETERMINATION OF CHINESE STANDARD REFERENCE MATERIAL——COAL FLY-ASH BY MONO-STANDARD NEUTRON ACTIVATION ANALYSIS

摘要: 应用单标法中子活化分析(MS-NAA)测定了中国标准参考物质——煤飞灰中的23种元素(Ag,Al,As,Ba,Ce,Co,Cr,Cs,Fe,Hf,K,La,Mg,Mn,Na,Rb,Sb,SmSr,Ta,Ti,V及Yb)。通过分析美国国家标准局(U.S.NBS)标准参考物质——煤(SRM-1632a)、都市微粒(SRM-1648)、果叶(SRM-1571)及意大利参考物质——空气飘尘来检验单标法的准确度。

Abstract: Mono-standard neutron activation analysis (MS-NAA) is applied to the determination of 23 elements (Ag, Al, As, Ba, Ce, Co, Cr, Cs, Fe, Hf, K, La, Mg, Mn, Na, Rb, Sb, Sm, Sr, Ta, Ti, V and Yb) in Chinese Standard Reference Material——Coal Fly-Ash. The accuracy of the MS-NAA procedure is checked by analyzing the U.S. NBS StandardReference Materials——Coal (SRM-1632a), Urban Particulate (SRM-1648), Orchard Leaves(SRM-1571) and Itlay Reference Material Mail Air Dust.
