摘　　要：用火焰原子吸收分光光度法,测定6种不同类型的冬小麦品种籽粒中铁、锰、锌微量元素的含量。结果表明铁、锰、锌的回收率分别为10309%,10290%和10119%,相对标准偏差(RSD)分别在394%,167%和269%以内,并以GBW08503小麦粉标准样品进行比较测定,结果满意。该方法简便、快速、准确。测定结果为研究小麦品种籽粒中微量元素的含量与小麦品质的关系提供依据。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.
