摘　　要：采用火焰原子吸收光谱法,测定了6种不同类型的冬小麦品种子粒中钾、钠、钙、镁宏量元素的含量。结果表明:钾、钠、钙、镁元素的相对标准偏差(RSD)分别小于0 77%、7 01%、3 82%、1 63%;并以小麦粉标准样品(GBW08503)进行比较测定,标准样品的测定值与标准值基本一致。该方法简便、快速、准确。The contents of K,Na,Ca and Mg magnificence element in six different kinds of the winter wheat seeds has been measured by flame atomic absorption spectroscopy. With the relatively standard deviations (RSD) of lower than 077%,783%,382% and 163% for K,Na,Ca and Mg, respectively, the determined values of standard sample were in agreement with the certified values of standard sample (GBW08503).This method is simple, rapid and accurate.
