摘要

头发因可以反映人体过去一段时间体内微量元素含量和状况[1],检测数据被广泛应用于医学、营养学和环境科学等方面;头发检测技术已经较成熟,但前处理耗费大量的时间,且有一定的危险性,石墨消解仪因一次消解的样品个数较多,温度连续可调,温度均匀性好,控温恒定,样品消解效果一致性好等特点,已被广泛使用。本文研究使用石墨消解仪消解头发的最佳消解条件。%The hair can reflect the trace element contents and status of human, and it is used in medicine, nutrition and environmental science research widely. The analytical technology of hair is mature, but the sample pretreated method is complex and dangerous. The Graphite -digestion device are widely used because of the feature of temperature uniformity, temperature accuracy and good digestion effect. The paper will research the best digestion condition of hair used Graphite- digestion device.
