| 摘 要： | 本文利用硒与４－硝基邻苯二胺在硫酸和高氨酸溶液中生成５－硝基－２，１，３－苯并硒二哇，且可以被萃取至甲苯中这一性质，用气相色谱法配合电子捕获检测器测定了甲苯中的５－硝基－２，１，３－苯并硒二唑，从而测定了硒的含量。该方法应用于人发中微量硒的含量测定，获得了满意的结果。

| Abstract: | Ths Se in hair was determinated by GC with ECD. According to the property that Se can be combined with 4--nitro-o-phenylene diamine for making out 5--nitro--2,1. 3--Se--benzimidazole which can be extracted into methyl benzene. By 5-tiro-2, 1,3-Se--benzimidazole' s testing the Se' s amount can be measured. |
