摘要
本文采用电感耦合等离子体质谱(ICP-MS)法测定四川石棉低品位碲矿中碲以及铋铜钴镍锑硒的含量,探究了高压罐消解法-ICP-MS测定低品位碲矿中Te、Bi、Cu、Co、Ni、Sb和Se七种元素的检出限、定量限、精密度和回收率高低。结果表明,该方法在测定七种元素时,检出限为0.008～0.437μg/L,定量限为0.027～1.450μg/L;相对标准偏差均低于7%,具有良好的精密度;两种样品加标回收率均在89.7%～106%之间,具有较高的重复性,分析结果准确可靠。同时该方法操作简便、可用于大批样品的处理,是一种高效、准确的测定低品位碲矿中各元素含量的方法。
An inductively coupled plasma mass spectrometry(ICP-MS) method used to determine the concentration of tellurium, bismuth, copper, cobalt, nickel, antimony and selenium in tellurium ore. The detection limit, limit of quantification, precision and recoveries of Te, Bi, Cu, Co, Ni, Sb and Se in lowgrade tellurium ore were explored by high-pressure tank digestion-ICP-MS. The results indicated that the detection limits were 0.008～0.437 μg/L and quantitation limits were 0.027～1.450 μg/L. A good precision was obtained with no exceeding 7% of relative standard deviation. The recoveries of two sample between89.7～106% showed high repeatability, accurate and reliable analysis results. At the same time, this method is easy to operate and can be used for treating large quantities of samples. It is an efficient and precise method for determination of various elements in low-grade tellurium ores.
