Abstract

Accurate and reliable data on microgram and nanogram quantities of some essential and toxic elements in most food articles are very scarce. Neutron activation analysis (NAA), with its essentially blankfree advantage, is a valuable approach in the field of determination of trace elements in different foodstuffs and diets. Accordingly, various radiochemical (RNAA) and instrumental (INAA) approaches have been developed in our laboratory for the element As, Cd, Co, Cu, Hg, I, Mo, Ni, Sb, Se, Sn, Th, U, V, and others, and verified by the analysis of compositionally appropriate certified reference materials.

摘要

关于大多数食品中某些必需元素和有毒元素微克和纳克含量的准确可靠数据非常稀少。中子活化分析（NAA）具有基本无空白的优势，是测定不同食品和饮食中微量元素领域的一种有价值的方法。因此，我们实验室针对砷、镉、钴、铜、汞、碘、钼、镍、锑、硒、锡、钍、铀、钒等元素开发了各种放射化学（RNAA）和仪器（INAA）方法，并通过对成分合适的有证标准物质的分析进行了验证。
