Abstract

The iron, manganese and zinc trace element contents of six different kinds of winter wheat seeds were studied by flame atomic absorption spectrophotometry. As a result, the rates of recovery of iron, manganese and zinc are 103.09%, 102.90% and 101.19%, respectively, and the relative standard deviations (RSDs) of Fe, Mn and Zn are smaller than 3.94%, 1.67% and 2.69%, respectively. Taking GBW08503 wheat flour as standard sample and carrying out comparative determination, the successful results were achieved. This method is very simple, rapid and accurate.

摘要

采用火焰原子吸收分光光度法研究了6种不同冬小麦种子中铁、锰、锌微量元素的含量。结果表明，铁、锰、锌的回收率分别为103.09%、102.90%和101.19%，铁、锰、锌的相对标准偏差分别小于3.94%、1.67%和2.69%。以GBW08503小麦粉为标准样品进行对比测定，结果成功。该方法简便、快速、准确。
