The determination of Aluminum (Al) in biological material by Instrumental Neutron Activation Analysis (INAA) contains some problems; (1) polyethylene bag enclosing specimen contains Al, (2) biological material includes the abundant phosphorus. Two elements interfere the Al determination by competing reactions, 28Si(n,p) and 31P(n,a), and the interference factors from each elements were 3.1x10(-3) and 1.0x10(-3), respectively. The Al concentrations in 18 biological reference materials and human tissues were determined by INAA.
用仪器中子活化分析（INAA）测定生物材料中的铝（Al）存在一些问题：（1）包裹样品的聚乙烯袋含有铝，（2）生物材料中含有大量的磷。这两种元素通过竞争反应干扰铝的测定，即28Si（n，p）和31P（n，α），且每种元素的干扰因子分别为3.1×10^(-3)和1.0×10^(-3)。通过仪器中子活化分析测定了18种生物参考物质和人体组织中的铝浓度。
