ICP-OES测定乌苏柳花茶中无机元素含量

摘要

[目的]测定乌苏柳花茶中无机元素含量.[方法]采用电感耦舍等离子体发射光谱仪(ICP-OES)测定新疆乌苏特产柳花茶中Al、B、Ba、Ca、Cu、Fe、K、Mg、Mn、Na、Ni、P、Si、Sr、Zn 15种无机元素含量.[结果]柳花茶中15种无机元素含量由高到低依次为K、Ca、P、Mg、Sr、Fe、Na、Zn、Al、Mn、B、Si、Cu、Ni、Ba,其中K、Ca、Mg、P含量较高,Na含量较低,具有潜在的维持人体正常血压、血脂的作用.[结论]该方法稳定性、精密度、准确性较高,可满足测定需要.%[Objective] To study the content of inorganic element in Liuhua tea.[Method] The content of 15 elements(Al,B,Ba,Ca,Cu,Fe,K,Mg,Mn,Na,Mo,Ni,P,Si,Sr and Zn) in Liuhua tea by ICP-OES were studied.[Result] K,Mg,Ca,P were rich in Liuhua tea,the content of Na was very low.The content order from high to low was K,Ca,P,Mg,Sr,Fe,Na,Zn,Al,Mn,B,Si,Cu,Ni,Ba.Liuhua tea had the potential to maintain the body's normal blood pressure and blood lipids.[Conclusion] The precision and accuracy of detection results were good,and meet the need for measurement.
