铝土矿样品分解方法和分析测试技术研究进展

铝土矿具有较强的化学稳定性,属于一种比较难分解的矿石,这给其分析测试带来一定困难。主要对近10年铝土矿样品分解方法和分析测试技术的研究情况进行了评述。对敞开酸溶法、微波消解法、高压密闭法、碱熔融法、氟化铵和氟化氢铵消解等样品分解方法以及电感耦合等离子体原子发射光谱法(ICP-AES)、电感耦合等离子体质谱法(ICP-MS)、X射线荧光光谱法(XRF)和激光诱导击穿光谱法(LIBS)等测定技术进行了总结,并对铝土矿样品的分解方法和分析测定技术的发展前景进行了展望。引用文献66篇。

Progress of sample digestion methods and analytical techniques for bauxite

Bauxite has strong chemical stability and belongs to a kind of ores which are hardly composed. It brings some difficulties to its analysis and determination.The progress in digestion methods and analytical techniques of bauxite sample in recent ten years was mainly reviewed. The sample digestion methods included acid digestion in open system, microwave digestion, high-pressure digestion, alkali fusion, NH₄F and NH₄HF₂ digestion. The analytical techniques included inductively coupled plasma atomic emission spectrometry (ICP-AES), inductively coupled plasma mass spectrometry (ICP-MS), X-ray fluorescence spectrometry (XRF) and laser induced breakdown spectroscopy (LIBS). In addition, the development of sample digestion methods and analytical techniques for bauxite samples were prospected. Total 66 references were cited.
