Instrumental Neutron Activation Analysis of Trace Elements in Some Food Spices Consumed In Tehran, Iran
Introduction There is a growing interest in determining the concentration of various elements in food spices. In the present study, the instrumental neutron activation analysis (INAA) was employed to measure the trace elements in 11 commonly food spices consumed in Tehran, Iran. Materials and Methods The levels of K, Mn, Na, Cl, V, Br, Al, and As were determined and their effects on human healt...

متن کاملStudy on trace impurity elements in highly purified iron and aluminum by neutron activation analysis.
Activation analysis was carried out on the purified iron and aluminum to study the behavior of trace impurities on purification process, and to estimate the purity of the purified samples. Thermal neutrons with high Cd ratio through D2O column or graphite column were used for the activation of samples to reduce the interference effects by fast neutrons, the reactions, (n, p) or (n, a), from mat...
متن کاملGradient centrifugation to isolate platelets for determination of trace elements by neutron-activation analysis.
A nonionic iodinated compound, Nycodenz, was used for density-gradient isolation of platelets before analysis for trace elements by instrumental neutron activation. The platelet samples were almost free from plasma and erythrocytes, and the trace element contribution from additives was insignificant for the elements investigated. The reproducibility of the trace element analysis in platelets at...
متن کاملDetermination and Application of Trace Elements
It is a well known fact that minera l plays an important role in the nutrition of animal and plant. The t race elements, which are a part of the mineral and exi st in a very small amount in the living bodies, include not only essential elements but also harmfu l and useless elements. In the researches up until now, physiological significance or essentiality for living body of such elements as c...
