Sulfur was determined in NBS Coal Fly Ash (SRM 1633) and Residual Fuel Oils (SRM's 1619, 1620a, 1634a) by radiochemical neutron activation analysis (NAA) using the /sup 34/S(n,..gamma..)/sup 35/S reaction. The /sup 35/S was separated from solutions of the standards by either cation-anion exchange on Dowex 50W-X8/Dowex 1-X8 or by adsorption on Al/sub 2/O/sub 3/. Liquid scintillation counting of aqueous solutions was used for /sup 35/S measurement. The /sup 35/Cl(n,p)/sup 35/S interference was corrected for by measurement of chlorine by instrumental NAA. The method may be applied to very small samples of fly ash or air particulates (<10/sup -3/ g). 1 figure, 5 tables.
