摘要
本方法采用HNO3-H2O2氧化、碳化有机物，再经HNO3-HClO4消解有机成分，对样品有机相中V、Al、Fe、Ca、Mg进行测定。方法可在较短的时间内快速测定含钒碳质页岩清洁提钒工艺有机相及水相中的V、Al、Fe、Ca、Mg五个项目数百件三千多个项目的分析测试，测量结果准确，加标回收率结果令人满意。方法在实际应用中产生良好的经济效益。
The sample was dissolved with mixed acids of HNO3 and H2O2. Then used the HNO3 and HClO4 to dissolved the organic consitituent. V, Al,Fe,Ca,Mg in the organic interfaces were measured by ICP-AES. The method could determine the V, Al,Fe,Ca,Mg at organic and aqueous interfaces in Cleaner Technology of Vanadium.Extraction from Carbonaceous Shale quickly. The method was used to determine several hundred samples. The accuracy and precision was satisfied. The method also contained a perfect economic benefit.
