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 کاملDetermination of multielements in a typical Japanese diet certified reference material by instrumental neutron activation analysis.
Multielements in a typical Japanese diet certified reference material prepared at the National Institute for Environmental Studies (NIES) of Japan, in collaboration with the National Institute of Radiological Sciences (NIRS) of Japan were determined by instrumental neutron activation analysis (INAA). Five samples (ca. 510-1000 mg) and comparative standards were irradiated for a short time (10 s...
متن کاملInstrumental neutron activation analysis (INAA) for steel analysis and certification
Addition of trace elements (intended or as impurities) in steel or alloys can completely change the properties of materials; thus, there is a necessity to have reliable analytical techniques to determine major and trace components in this type of material. Also, to solving problems with quality control/quality assurance (QC/QA) in this subject, appropriate certified reference materials should b...
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...
