FAAS法测定保健酒中8种无机元素含量

Determination of eight inorganic elements in the health wine by flame atomic absorption spectrophotometry(FAAS)

测定不同地区保健酒中无机元素的含量。采用火焰原子吸收光谱法（FAAS）技术分别测定了6种保健酒中8种无机元素的含量,样品用（v/v=HNO3/H2O）6.5mL/L硝酸稀释后直接进样测定。所测试样中8种元素的相对标准偏差（RSD）均RSD%≤5%,各元素加标回收率均在80.4%~114.0%。不同地区保健酒均中含有较丰富的Ca、Mg元素,几乎所有的待测样品中均未检测出重金属元素Cu、Pb、Cr;此外,贵州地区保健酒中的Ca、Mg、Mn元素高于其他地区,侗家奇液还含有丰富的人体必需营养元素Zn、Fe。此法快速、简单的检测了不同保健酒中8种无机元素的含量,为保健酒的营养因子的客观评价提供了实验依据。

To investigate inorganic elements in the health wines.They were diluted with（v/v=HNO3/H2O） 6.5ml/L HNO3 and analyzed for 8 inorganic elements in different producing region health wine by the flame atomic absorption spectrometry（FAAS）.It was results showed that for all elements of relative standard deviation（RSD） was RSD%≤5% and the recoveries of spiked samples were in the range of 80.4%~114.0%.It was indicated that the different areas of health wine all contained rich Ca,Mg and almost all of the tested samples were not detected heavy mentals Cu,Pb,Cr.The others,containing of Ca,Mg,Mn,elements in Guizhou health wine were more other region,in particularly,Dongjiaqiye wine contains rich essential nutrients Zn,Fe.The method was simple and fast,which was to investigate content of eight different health wine inorganic elements for the health assessment of nutritional factors provide an experimental basis.
