摘要
采用氢氟酸溶矿-酒石酸浸取-醋酸乙脂萃取,干扰杂质可通过盐酸反萃取除去,方便快速,与经典分析方法结果相符,特别适用于铌含量在0.000X-0.001%的样品分析。
In the testing, the ore is resolved by fluohydric acid, humidified with tartaric acid and extracted by ethyl acetate. And the disturbance impurities can be removed by reversal extraction with hydrochloric acid. This method is not only convenient but also rapid. The analysis result is consistent with that of the classic analysis method, which is especially suitable to the samples with Nb 0. 000X -0. 001%.
