矿业中砷的分析方法概述

摘要

Arsenic existed in the nature widely as a odourless , tasteless and poisonous elements , which not only polluted the environment and water resources , but also endangered human health if arsenic was released in mining industry.So it was necessary to test the arsenic content of materials and waste water.The analysis methods of arsenic in mining industry were summarized , including volumetric method , colorimetric method , atomic absorption spectrometry AFS, electrochemical method , X-ray fluorescence method , inductively coupled plasma mass spectrometry , etc.Some features of these analysis methods were discussed.The combined techniques in separation and analysis of arsenic speciation were prospected.%砷作为一种无臭无味的剧毒元素，在自然界中广泛存在。在矿业中，砷的释放，不仅污染环境及水资源，而且危害人类健康，因此必须对原料及废水中砷含量进行检测。综述了矿业中砷的主要分析测试技术，主要是容量法、比色法、原子吸收光谱法、原子荧光法、电化学方法、 X-射线荧光法、电感耦合等离子体质谱法等，论述了这些分析方法的一些特点，展望了联用技术在矿业砷测定中的应用前景。
