【摘要】 采用X射线荧光光谱半定量分析软件IQ+对圆白菜样品进行主、次量元素含量分析,以圆白菜中主要营养成分含量为依据,模拟其平均分子式。同时考察平衡项分子式的影响。结果表明,采用模拟的平均分子式作为平衡项处理,测定结果与给出的参考值较吻合。更多还原

【Abstract】 X-ray fluorescence spectrometric method for semi-quantitative determination of major and minor elements in cabbage is reported. The average molecular formula is simulated base on content of major nourishment in cabbage, at the same time, The influencing factor of molecular formula on balance is studied. The result shows that the measurement results agree well with standard values by choosing simulative molecular formula on balance.更多还原
