【摘要】 铈硼硅石是一种罕见的稀土矿物,由于它含有某些化学性质近似的元素,故分析难度较大。本文研究了应用纸色层法和离子选择性电极法对铈硼硅石中某些主要成分和微成分的分离和测定条件,设计了较合理的铈硼硅石微量全分析流程。该流程也适合类似矿物的分析,与常法比较,本法具有快速、准确、成本低和用样少等优点。更多还原

【Abstract】 Stillwellite is a rare REE mineral. Stillwellite is difficult to analyze because it contains some chemical elements which are similar in chemical properties and may interfere each other during analysis. This paper deals with the conditions of separating and determing the main components in stillwellite by paper chromatography and ion selective electrode technique. A more reasonable procedure for microanalysis of stillwellite has been developed. The method is also applicable to similar minerals and it has the advantages of high speed, accuracy, lower cost and small specimen requirement.更多还原
