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

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.
