DETERMINATION OF TRACE-ELEMENTS OF EGYPTIAN CROPS BY NEUTRON-ACTIVATION ANALYSIS .2. TRACE-ELEMENTS IN UMBELLIFERAE AND LEGUMIROSAE FAMILIES

Neutron activation analysis, NAA, a high resolution Ge(Li) gamma ray spectrometer was used to determine the concentration of Al, As, Au, Br, Ca, Cd, Co, Cr, Cu, Fe, La, Mn, Mo, Sb, Se, W, and Zn in Cumin, coriander, carrots, and Daucus carrota (Umbelliferae Family), alfalfa, Kidney bean, Phaseolus sativus, Phaseolus vulgaris, bean, lenses, and fenugreek (Legumirosae Family). Multielement determination technique on destructive and nondestructive samples was followed. This method is simple, precise and sensitive to 17 trace elements. © 1979 Akadémiai Kiadó.
