采用HNO3-H2O2混合酸体系微波消解及电感耦合等离子体-质谱法,消解唐古特乌头样品,测定其中Mn、Fe、Co、As、Ni、Se、Cu、Zn、V和Cr共10种微量元素。探讨了样品消解的条件,通过加标回收实验,回收率为94.08%—103.50%,验证了分析数据的可靠性。结果表明,该法具有快速、简便、准确度高、能同时分析多元素的优点,结果令人满意。 The samples of Tangut ugliness were digested with HNO3-H2O2 mixed acid system by microwave digestion and inductively coupled plasma-mass spectrometry. Ten trace amounts of Mn, Fe, Co, As, Ni, Se, Cu, Zn, V and Cr element. The conditions of sample digestion were discussed. The recoveries were 94.08% -103.50% by spike recovery test, which verified the reliability of the analytical data. The results show that this method is fast, simple, accurate and can analyze the advantages of multiple elements at the same time. The result is satisfactory.
