摘要
本文介绍了用石墨炉原子吸收法测定人发中硒，并测定了比对发样及１２０名中学教师的发样。发硒范围０．１５～１．００ｍｇ／ｋｇ，中位数０．４３ｍｇ／ｋｇ。本法灵敏度为２．９６ｎｇ／ｍＬ，变异系数２．４％～６．７％。
Determination of selenium in human hair by GFAAS has been described in this paper,Hairs from 120 middle school teachers were determined.The results are 0 15～1 00 mg/kg and the median is 0 43 mg/kg. The sensitivity of this method is 2 96 ng/mL and the relative standard deviation is 2 4%～6 7%
