中文摘要:

      地球化学样品中钒的测定方法主要有原子吸收光谱法、等离子体发射光谱法（ICP-AES）、电感耦合等离子体质谱法（ICP-MS）和X射线荧光光谱法.选用国家一级标样，分别用4种方法测定样品含量值，依次对方法检出限、准确度、精密度、加标回收率作比较.经对比，4种方法测定值与推荐值都基本吻合.等离子体发射光谱法检出限低，线性范围更宽，准确度与精密度更好，更适用于地球化学样品中钒批量的测试.

英文摘要:

      The determination methods of vanadium in geochemical samples include atomic absorption spectrometry, plasma emission spectrometry(ICP-AES), inductively coupled plasma mass spectrometry(ICP-MS), and X-ray fluorescence spectrometry. Four national standard samples were used to determine the content of samples, and the detection limits, accuracy, precision and recovery rates were compared. By comparison, the measured values of the four methods are basically in agreement with the recommended values. The plasma emission spectrometric method has a low detection limit, a wider linear range, a better accuracy and precision, and is more suitable for testing vanadium batches in geochemical samples.
