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 کاملRapid method for the determination of trace fluoride and activation of ion-selective electrode.
A method for activating ISE is proposed that can allow determination of the fluoride concentration at ng mL(-1) level with good precision and accuracy. Fluoride ISE is activated in 0.5 mol L(-1) HClO4 medium and then fluoride is determined in the same medium. The linear range for the determination of fluoride is between 1.00 x 10(-2)-1.00 x 10(-7) mol L(-1), and the detection limit of the metho...
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 of bromides in blood by neutron activation analysis.
A method is described for the determination of bromides in biological samples using neutron activation analysis. The specificity of this method eliminates sources of interference from other halogens and contamination of analytical agents with extraneous bromide. In duplicate samples of blood, at varying concentrations of potassium bromide, the mean difference was 4.5% ±1.95 and the mean of the ...
