Multielemental neutron activation analysis of water samples from Nagpur City and environmental standards
Multielemental instrumental neutron activation analysis has been employed for the determination of >20 elements (Ag, Au, Br, Co, Cr, Cs, Eu, Fe, Hf, Hg, Ir, La, Lu, Na, P, Sb, Sc, Se, Ta, Tb, Te, Th, Zn, Zr) in water samples from different locations in Nagpur city in Central India. Several environmental standards from NIST (U.S.A.), NIES (Japan) and IAEA (Vienna) were also analyzed for accuracy determination. After preconcentration by evaporation, the samples were irradiated with thermal neutrons at ∼ 1013 n·cm−2s−1 in CIRUS reactor for a day and one week and counted by high resolution γ-ray spectrometry. Elemental concentrations of most elements in the standards are in good agreement with the certified values.
