摘要
本文用ＩＣＰ－ＡＥＳ法同时测定富铬酵母中Ｋ、Ｆｅ、Ｐ、Ｚｎ、Ｃｒ、Ｃｕ、Ｍｎ、Ｃｏ、Ｂａ、Ｓｒ、Ｖ、Ｎａ、Ｍｇ、Ｃａ１４种元素的含量。结果表明，富铬酵母中的铬对其他元素的浓度有一定影响，并且，Ｋ、Ｍｎ、Ｐ、Ｖ、Ｍｇ、Ｃａ的浓度明显低于普通酵母。
An ICP AES method was established for the determination of 14 elements in chromium rich and normal brewer′s yeast.The RSDs of two standard reference materials were 0 5% 3 2% and 0 4% 3 4%,respectively.The results showed that chromium contents could affect the concentrations of other elements in chromium rich brewer′s yeast.The concentrations of K,Mn,P,V,Mg and Ca in chromium rich brewer′s yeast were significantly lower than those in normal brewer′s yeast.
