Neutron activation analysis of some biological environmental materials

Determination of 129I in seawater and some environmental materials by neutron activation analysis

A neutron activation analysis method with pre-irradiation separation and post-irradiation purification is presented for the determination of 129I content and 129I/127I ratio in some environmental samples, such as seawater, seaweed, grass and soil. An evaporation concentration followed by solvent extraction was used for the separation of iodine from seawater, and alkaline ashing or alkaline fusi...

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...

Determination of chromium in biological materials by radiochemical neutron activation analysis (RNAA) using manganese dioxide

A procedure based on radiochemical neutron activation analysis was developed for the determination of chromium in biological materials. The procedure consists of irradiation of reference and test samples in a nuclear reactor, microwave sample digestion, selective and quantitative radiochemical separations of chromium and gamma-ray spectrometric measurement of 51Cr. Separation of chromium from t...
