Abstract: | Multielemental neutron activation analysis was used for the determination of Al, As, Au, Br, Ca, Cd, Co, Cr, Cu, Fe, La, Mn,
Mo, Sb, Se, W and Zn in African tea, and lady's fingers (Malvaceae Family), ginger (Zingiperaceae Family), canella bark (Laureceae
Family), black pepper (Piperaceae Family), cucumber seeds and vegetable marrow seeds (Cucurbitaceae Family), tomatos seed
(Solanaceae Family), safflower seeds (Compositae Family), jew's mallow seeds (Tiliaceae Family) and sesame (Pedaliaceae Family).
Trace elements determination was made to the analysis of destructive (using super pure nitric acid and adsorbing the metal-APDC
and metal-Dz complexes on activated charcoal) and nondestructive (dry seeds) samples. The method is simple, precise and sensitive
for the determination of microamounts of the elements (ppm to ppb). |
