摘要
建立快速石墨消解-电感耦合等离子体质谱法测定土壤中铜、铅、镉、钴4中重金属元素的方法。采用盐酸-硝酸-氢氟酸消解体系运用石墨消解仪进行快速消解,应用电感耦合等离子体质谱仪测定土壤铜、铅、镉、钴元素,结果表明,铜、铅、镉、钴的精密度及准确度均能满足测定要求,为土壤中铜、铅、镉、钴的测定提供了一种快速可靠的消解方法。
A rapid graphite digestion-inductively coupled plasma mass spectrometry method was established for the determination of heavy metal elements in soil of copper,lead,cadmium and cobalt.The determination of copper,lead,cadmium and cobalt in soil by inductively coupled plasma mass spectrometer(ICP-MS)was carried out by using graphite digestion apparatus.The results showed that the precision and accuracy of copper,lead,cadmium and cobalt could meet the requirements.
