Description
A method was developed for determination of arsenic, antimony and selenium in water samples, based on neutron activation and separation by coprecipitation with bismuth sulfide. Experiments performed with the aid of radioactive tracers proved that As(III), Sb(III) and Se, either as Se(IV) or Se(VI), were quantitatively coprecipitated in 1.2 N HCl, provided they were present in masses larger than 10 ng, 50 ng, and 20 ng, respectively; 24Na and 82Br were collected at minimum percentages (0.5 and 2) when using hold-back carriers, whereas no appreciable coprecipitation of 32P was observed. Interferences by other trace elements were also investigated, finding that they were negligible in most of the cases. The method was applied to the analysis of underground water samples from the province of Cordoba (Republica Argentina). The characteristics of this method and the results are discussed. 12 references, 2 tables
