| 摘 要： | 用电感耦合等离子体-原子发射光谱法测定红景天中锌、铁、锰和钛等元素。使用与分析样品基体相接近的标准样品和控制一致的测定条件,克服了物理干扰和基体效应的影响,选择波长为233.0,273.9,257.6,334.9nm4条谱线分别作为测定锌、铁、锰和钛的分析线,测得4种元素的检出限(3s)为0.004—0.05μg/mL。本法测定红景天中4种金属元素的含量,相对标准偏差(n=7)在2.2%—4.2%之间,加标回收率在96.4%—115.2%之间。

| Abstract: | The contents of Zn,Fe,Mn and Ti in rhodiola were determined by ICP-AES.Physical interference and matrix effect were eliminated by standard samples which have matrixes similar to the sample＇s and analyzing under the same analytical conditions.Wavelengths of 233.0,273.9,257.6nm and 334.9nm were selected as analytical line for the determination of Zn,Fe,Mn and Ti respectively.Detection limits （3s） are in the range of 0.004—0.05μg/mL for the four metal elements.The proposed method was used for the determination of four metal elements in rhodiola,and RSD（n=7） was between 2.2% and 4.2% respectively ,recovery was in the range of 96.4%—115.2%. |
