摘要: Industrial fertilizers were used to study selected essential and non-essential metals by two analytical techniques, namely atomic absorption spectroscopy neutron activation analysis. Out of eight Pb, Cu, Fe, Zn, Ni, Cd, Mn Cr, which determined technique, Fe showed maximum concentration, whereas Cd Pb minimum value. In the case analysis, 16 elements Co, Th, Sc, La, Ba, Rb, Cs, Sb, Yb, Ce, Mn, Na Eu analyzed. this group, exhibited concentration value, while Sb Zn four commonly studied techniques. Within highest values, lowest was shown in Cr. The comparison overall data generally lower concentrations trace nitrogenous as compared potash phosphatic fertilizers.
