摘　　要：用盐酸-硝酸-氢氟酸-高氯酸分解石煤钒矿试样，电感耦合等离子体发射光谱法（ICP-AES）测定主、次、痕量元素Al、Fe、Ca、Mg、P、Ti、S、Co、Cu、Mn、Ni、V。本研究课题首次开展550℃灼烧样品后再按实验方法进行测定样品；新特点是在样品溶解好后加入过氧化氢，过氧化氢既有氧化性又有还原性，既能还原某些元素使其沉淀溶解，又没引进干扰成分，使测定结果更加准确可靠；磷与其他元素的测试合并为一次实验过程，大大减少了劳动强度，节约了成本，适合于大批样品的分析测试。方法准确、可靠，提高了工作效率，结果令人满意。in this research, samples are decomposed by hydrochloric acid, nitric acid, hydrofluoric acid, perchloric acid to, and the main, second, and trace elements-Al, Fe, Ca, Mg, P, Ti, S, Co, Cu, Mn, Ni and V are determined by inductively coupled plasma emission spectrometry （icp-aes）. this research for the first time to burn samples over 550℃before determining the samples according to the experimental method; new feature is adding hydrogen peroxide after the samples dissolved, and hydrogen peroxide is both oxidizing and reducing, can reduce some elements to dissolve them, without any interference components, making the determination results more accurate and reliable;the tests of phosphorus and other elements are united into one experimental process, greatly reducing the labor intensity, saving the cost, which is suitable for the large number of sample analysis. this method is simple, fast, and the result is satisfactory.
