中文摘要: 以硝酸和过氧化氢混合溶液为消解溶剂,利用微波消解法制备鲢鱼肌肉样品溶液,再应用全谱直读电感耦合等离子体发射光谱测定技术(ICP-OES),对鲢鱼肌肉中所含的矿物元素进行较为全面的定性定量分析。定性结果显示,鲢鱼肌肉中含有19种矿物元素,分别是K,Ti,Al,Ga,B,Ba,Ca,Cd,Cr,Cu,Fe,Mg,Mn,Na,P,Pb,S,Sr,Zn等。定量结果显示,ICP-OES定量分析线性范围宽,可达2个数量级以上;工作曲线线性相关系数在0.999以上;样品测定RSD值在0.44 % ~ 11.83 %之间,大部分在5%以内;除了一个元素以外,回收率测定结果都在(100±10)%以内;测定结果可为相关应用研究提供参考数据。

Abstract:Taking mixed solution of nitric acid and hydrogen peroxide as the digestion solvent, silver carp muscle sample solution was prepared by microwave digestion method, and then the comprehensive qualitative and quantitative analysis of the mineral elements contained in the silver carp muscle was detected by directreading inductively coupled plasma atomic emission spectroscopy (ICP-OES). The qualitative results showed that silver carp muscle contains 19 mineral elements, that is K, Ti, Al, Ga, B, Ba, Ca, Cd, Cr, Cu, Fe, Cr, Cu,Fe,Mg,Mn,Na,P,Pb,S,Sr,Zn and so on. The quantitative results showed that ICP-OES analysis has wider linear range up to 2 orders of magnitude , and the linear correlation of the working curve is good with correlation coefficient more than 0.999. The RSD value is between 0.44% and 11.83%, mostly within 5%. Except for one element, the recovery rate of determination is in (100±10)%. The determination results provide reference data for the relevant application study.
