| 摘 要： | 竹叶样品置于聚四氟乙烯罐中,加入硝酸及过氧化氢后在微波消解仪中按设定程序加热消解。所得样品溶液定容至25mL后用电感耦合等离子体原子发射光谱法测定其中铬、锌、镍、钴、铁、硼、锰、铜和锶等9种元素的含量。9种元素的质量浓度在0.05～2.00mg.L-1范围内与其发射强度呈线性关系,方法的检出限(3s)在0.04～0.50μg.g-1之间。方法应用于分析了一种杨树叶标准物质(GBW 07604),所得9种元素的测定结果与证书值相符。方法的回收率在87.0%～107.6%之间。

| Abstract: | The sample of bamboo leaves was digested with HNO3 and H2O2 in a teflon vessel and heated in the microwave digester under the prescribed working program.The sample solution obtained was made up to 25 mL and used directly for the ICP-AES determination of 9 essential elements(Cr,Zn,Ni,Co,Fe,B,Mn,Cu and Sr).Linear relationships between values of emission intensity and mass concentration of 9 elements were found in the same range of 0.05-2.00 mg·L-1,with detection limit(3s) in the range of 0.04-0.50 μg·g-1.The proposed method was used to analyze a CRM of poplar leave(GBW 07604),giving results in consistency with the certified values.Values of recovery of the method found were in the range of 87.0%-107.6%. |
