现代的分析技术如原子吸收(AAS),高频等离子体(ICP—AES)等方法,不仅快速,而且检出限达到 ppb 级,是进行痕量分析的有效手段,这些方法大多数是液体进样,对固体样品,必须溶解成液体,这个过程被分析化学工作者称为样品的预(前)处理,或称样品的消解,即使是液体样品,为消除干扰,也往往需进行消解,但是,样品的预处理技术,
Modern analytical techniques, such as atomic absorption (AAS) and high-frequency plasma (ICP-AES), are not only fast but also have a detection limit of ppb, which is an effective method for trace analysis. Most of these methods are liquid In the case of a solid sample, it must be dissolved into a liquid. The process is referred to by a chemist as the pre-treatment of the sample, or the digestion of the sample. Even a liquid sample is often subjected to digestion to eliminate interference. However, , Sample pretreatment technology,
