增压溶样—ICP—AES法同时测定茶叶中多种微量元素含量的研究
Determination of Multiply Trace Elements in Tea Leaf by ICP-AES and Sample Dissolution under Pressure
【摘要】 研究了增压溶样-ICP-AES法同时测定茶叶中Al,As,Ba,Cd,Cu,Fe,Mn,Ni,Pb,Se和Zn等12种矿质营养元素及重金属元素,确定仪器最佳工作参数,并对基体干扰及共存元素的光谱干扰等进行了探讨。方法准确度、精密度符合痕量分析要求;灵敏度适合进行茶叶分析。
【Abstract】 The 12 trace elements,including Al,As,Ba,Cd,Cu,Fe,Mn,Ni,Pb,Se and Zn in tea leaf were determined by ICP-AES and sample dissolution under pressure.The experiment factors including interference of coexisting elements and instrument parameters have been investigated.A simple and rapid method with high accuracy and good precision for the simultaneous determination of multiply trace elements in tea leaf has been established and the result was satisfactory.
