电感耦合等离子体原子发射光谱法测定样品中的砷锑铋

Determination of arsenic,antimony,bismuth in ore by inductively coupled plasma atomic emission spectrometry

我国锑矿储存量比较多,分布范围具有广泛性特点,锑元素通常和金、铜、镍等元素处于共生关系,我们需要测定其中锑元素含量。当前在测定过程中广泛利用容量法和光度法和原子吸收光谱法等。在对锑矿石锑含量检测的时候常用容量法,但是这一方法很难明确滴定终点,甚至会对检测数据产生干扰。电感耦合等离子体发射光谱法在近些年开始推广利用,可以对矿石精密度进行检测,而且具有较高的灵敏性和稳定性等优势,可以在金属矿石检测中推广利用,但是在矿石砷、锑、铋含量检测中应用相对较少。本文分析了电感耦合等离子体原子发射光谱法测定矿石中的砷锑铋,对于实际工作发挥参考作用。

China has a relatively large reserve of antimony ore,with a wide distribution range.Antimony is usually in a symbiotic relationship with elements such as gold,copper,and nickel,and we need to determine its content.Currently,volumetric,photometric,and atomic absorption spectroscopy are widely used in the measurement process.The volumetric method is commonly used for detecting antimony content in antimony ores,but this method is difficult to determine the titration endpoint and may even interfere with the detection data.Inductively coupled plasma emission spectroscopy has been widely used in recent years,which can detect the precision of ores and has advantages such as high sensitivity and stability.It can be widely used in the detection of metal ores,but its application in the detection of arsenic,antimony,and bismuth content in ores is relatively limited.This article analyzes the determination of arsenic,antimony,and bismuth in ores using inductively coupled plasma atomic emission spectroscopy,which provides a reference for practical work.
