摘要

摘要利用30 kW研究堆的热中子和超热中子进行仪器中子活化分析,测定了市场上婴幼儿食品中某些必需元素的浓度。元素Ca、Cl、Fe、Mn、Mg、K、Na、V、Zn、Br和I在尼日利亚广泛销售的四种婴儿食品中以不同的比例被发现。测量结果与生产商报价的比较表明,所采用的实验程序可用于常规控制和监测目的。

Routine Monitoring of Market Infant Foods by Neutron Activation Analysis with a Low-Power Reactor
Abstract Instrumental neutron activation analysis technique with thermal and epithermal neutrons from a 30 kW research reactor has been used to determine the concentration of some essential elements in market infant foods. The elements Ca, Cl, Fe, Mn, Mg, K, Na, V, Zn, Br, and I were found in various proportions in four infant foods widely sold in Nigeria. A comparison of the measured results and producer's quoted values indicates that the adopted experimental procedure can be used routinely for control and monitoring purposes.
