摘要
用电感耦合等离子体发射光谱仪（ICP）测定了湛江地区产的中药茅根微量元素的含量。结果表明，其钙、镁、铁、锌等元素的含量都比较丰富，测定方法的相对标准偏差为0．12％～4．03％，回收率为97．0％～102．0％，本法简便、快速，具有较高的准确性和重现性，适用于实际分析。
The content of trace elements in Baimaogen was determined by ICP atomic emission spectroscopy. The result showed that the content of calcium, magnesium the relative standard deviation of this measurement was 0. 12% ~ 4.03% was 97.0% ~ 102.0%. , iron and zinc was abundant, , the recovery rate of samples
