APPLICATION OF k0-INAA TECHNIQUE FOR THE ANALYSIS OF ESSENTIAL AND BENEFICIAL HEAVY ELEMENTS IN SOIL
Keywords:
k0 – INAA, nuclear reactor, essential mineral elements, beneficial heavy elements, plant growthAbstract
The researchers analyzed the essential and beneficial heavy elements in soil that improve plant growth,
development and other functions in this study using k0 – INAA technique. The use of k0 – Instrumental
Neutron Activation Analysis (k0 – INAA) technique has become a veritable tool for multi-element analysis.
This method has been applied in this present study to assess essential mineral elements and beneficial heavy
elements that supports plants growth of fifteen (15) samples collected from Safana, Dan Musa and Kankia,
LGAs of Katsina State. The samples were properly prepared together with the standard reference material
(NIST Coal Fly Ash 1633b) and were irradiated at a thermal power level of 31.0 kW corresponding to a
neutron flux setting of 2.5 x 1011 cm-2 s-1 and 5.0 x 1011 cm-2 s-1 for the outer and inner irradiation channels
respectively using the Nigeria Research Reactor – 1 (NIRR – 1) at the Centre for Energy Research and
Training, Zaria. After irradiation, the samples were counted using a high-purity germanium detection system
(GEM 30195 coaxial detector) and the concentrations of eleven elements (Mg, Ca, Ti, V, Mn, Na, K, Cr, Fe,
Co and Zn) from the samples and that of NIST Coal Fly Ash 1633b were measured using the k0 – IAEA
program. The result of the NIST Coal Fly Ash 1633b was in agreement with that of the certified values. The
concentrations of the elements measured from the samples shows that these elements are sufficient for plant
growth, except that some of
