电感耦合等离子体发射光谱法测定矿石中钽铌
Determination of Ta and Nb in Ore by ICP-AES
摘要
Abstract
The method adopts sodium oxide molten to decompose sample, a great quantity of metal ion shall be separated under alkaline condition, tantalum and niobium shall be formed to tannin complexes under weak acidity condition, which shall be precipitated after boiling, accordingly, separation and enrichment aim can be reached; after filtration, scrubbing and burning, as well as desiliconizing by hydrofluoric acid, niobium and tantalum shall be made into hydrofluoric acid solution, which shall be determined by ICP-AES spectrometer.关键词
