摘要
采用HNO3-H2O2混合酸，密闭微波消解制样，ICP—AES、ICP—MS测定茶叶中P、Zn、Fe、Mn、Mg、Ca、B、Cr、Co、Ni、Cu、Mo、Cd、Pb等14种微量元素含量，建立了对植物样品中多种元素进行同时测定的方法。经国家植物标准物质验证，方法具有较好的准确性和重现性，操作流程短，检出限低，基体干扰小，RSD≤10％，加标回收率在90％～110％之间。可用于植物样品的批量分析。
Under the sample preparation of microwave - closed digestion, the authors determinate contents of 14 kinds of trace elements including P, Zn, Fe, Mn, Mr, Ca, B, Cr, Co, Ni, Cu, Mo, Cd, Pb in tea by ICP-AES and ICP-MS, establish the simultaneous measurement on several elements in vegetation sample. Compared with the standard material, the method has great accuracy and repeatability, short procedure, low detection limit and matrix interfering. The precision is below 10%, the recovery rates are between 90% and 110%. It is applied to a small quantity of analyses in.,yegetation sample.
