| 摘 要： | 采用HNO3 H2O2酸溶体系对动物饲料样品进行微波密闭消解，利用电感耦合等离子发射光谱法（ICP AES）对样品中Ca、S、P、K、Mg、Na、Fe、Cu、Mn和Zn等无机元素含量进行测定。结果表明，该方法的相对标准偏差均小于5%；通过添加标准回收试验，回收率为94.7%～114.3%。因此，该方法具有良好的准确度和精密度，通过验证分析数据的可靠性，认为可满足动物饲料样品多元素同时检测的要求，为研究动物饲料矿物质元素含量以及在生产中科学应用矿物质元素与添加剂提供技术支持。

| Abstract: | The experiment was conducted to determine the contents of inorganic elements including Ca,S,P,K,Mg,Na,Fe,Cu,Mn,Zn,Co,and Mo in formula feed from Ningxia University by ICP-AES using high pressure system-sealed microwave digestion.The sample of feed was digested with HNO3-H2O2 acids system.The operation would be simplified,and the blank value would be decreased following the above measures.This study showed that the relative standard deviation was below 5% for all the elements.The recovery was between 94.7% a... |
