摘　　要：采用硝酸作为消解液,用微波消解、ICP-AES法测定了酸鱼中钾、钠、钙、镁、铁、锌、磷、锂、锶9种元素的含量,从营养元素的角度为酸鱼的营养价值研究提供科学数据。结果显示,各元素回收率(n=7)在88.5%~110%之间,相对标准偏差(n=7)0.05%~8.2%之间,该法具有很好的精密度和准确度。The sample was digested with HNO3,and night elements(K、Na、Ca、Mg、Fe、Zn、P、Li、Sr)in Sour fish were determined by Microwave digestion-ICP-AES,which offer scientific data of treatment of nutritional value of Sour fish from the perspective of nutrient elements.The results showed that the recovery(n=7)is 88.5%~110%,and the RSD(n=7)is 0.05%~8.2%,The method has good precesion and sensitivity.
