| 摘 要： | 水系沉积物、土壤等试样用HF-HCl-HNO3-HClO4混酸消解后，以8％（v／v）HNO3溶解于渣，建立了测定地球化学样品中La，Y，Ba 3种微量元素的电感耦合等离子体发射光谱（ICP-OES）方法。方法测定限（μg／L，10SD）为：La 6．0，Y 1．0，Ba 1．0。精密度（RSD％，n=11）为：0．20～1．50，经国家一级地球化学标准物质的分析验证，结果与标准值吻合，该方法现已用于区域化探试样的分析。

| Abstract: | An inductively coupled argon plasma optical emission spectrometers （ICP- OES） method is established to determine 3 microelements, such as La, Y and Ba. The geochemical samples were prepared by decomposding with the mixture of HF - HCl - HNO3 - HClO4, and then dissolving the residue with 8 （V/V）HNO3. Determination limit of this method is in range of 1-6 μg/L （10SD）, La 6.0, Y 1.0 and Ba 1.0. The precision degree is 0.20-1.50 （RSD%, n= 11）. The analysis results were in good agreement with the certified values. The method has been applied in analyzing regional geochemical survey samples. |
