人头发中硒的多少可以做为人体内微量硒的一个指示物,而且人头发样品易采取、便于保存、运送和少受沾污。已报导的人头发中Se的分析多用中子活化法等。中子活化法虽有明显优点,但设备难得,推广应用不便。本文讨论了氢化物发生—无色散原子荧光法用于人头发中微量硒测定的条件、样品处理方法、干扰元素的影响等问题。仪器与试剂 YD—2型无色散原子荧光分析仪(西安无线电八厂)和WB—2型微波发生器(。
How much selenium in human hair can be used as an indicator of trace selenium in the human body, and human hair samples are easy to take, easy to preserve, transport and less contaminated. Has been reported in the human hair Se analysis of multiple neutron activation method. Although neutron activation method has obvious advantages, but the device is rare, the promotion of application of inconvenience. This article discusses the hydride generation - non-dispersive atomic fluorescence spectrometry for determination of trace amounts of selenium in human hair conditions, sample handling methods, the impact of interfering elements and other issues. Instruments and reagents YD-2 non-dispersive atomic fluorescence spectrometer (Xi’an Radio eight plants) and WB-2-type microwave generator (.
