摘要
经试验研究，选定了分析地质样品中痕量硒的测定体系，建立了切实可行的分析方法，该方法不需分离，直接测定，灵敏度高，干扰少，方法测定下限可达０．０２μｇ／ｇ，进行了部分标样分析，结果令人满意。
After detailed study ,an optimum system for the determination of selenium in geological samples was developed and a reliable analytical method was established.No separation was needed and the method was highly sensitive with few interferences.The determining limit of the method was 0.02μg/g.Some standard reference materials were analysed and satisfactory results were obtained.
