放射性同位素x射线荧光分析仪是近十多年来世界上发展迅速的一项元素快速分析新技术。它具有体积小、重量轻、操作方便、分析速度快、不用试剂和不破坏样品等优点,能对固体、粉末、液体等不同样品中的元素含量进行直接测定,对于中、高含量样品更为适用。我们用此方法对铁精矿中元素铁进行了测定,收到了较好的效果。本文对此简述如下。 Radioisotope x-ray fluorescence analyzer is a rapidly developing elemental rapid analytical new technology in the world for more than ten years. It has the advantages of small size, light weight, easy operation, fast analysis speed, no reagents and no damage to samples, etc. It can directly measure the content of elements in different samples such as solid, powder and liquid, Be applicable. We use this method for the determination of iron in iron concentrates, received good results. This article is summarized as follows.
