Evaluation of Elemental Uptake of Citrus reticulata by Nuclear Analytical Techniques

Sneha P. Tenpe, D. V. Parwate

Citrus reticulata (mandarin) plant parts and soil have been opted for elemental evaluation by INAA with comparator and k0 method. Two reference material Soil-7 (IAEA) and apple leaves (SRM1515) were used as standards. Sodium was estimated by irradiation of samples in Am-Be source followed by counting on NaI(Tl) detector. Samples were also irradiated in KAMINI reactor, IGCAR, Kalpakkam and radioactive assay was carried out using HPGe detector coupled with 5MCA. Concentration of Na, Al, Mn, Ca, Fe, Sr, Sm, Sc, La, Th, Br, K, Zn, Ce were determined by NAA and in all 15 radicals were identified by XRF for same samples. It has been seen that soil with certain mineralogical and chemical make-up behaves respectively for availability of micronutrients
