建立了钢渣中多种矿质元素的检测方法。钢渣样品经HNO3-HF-HClO4消化,采用电感耦合等离子体质谱(ICP-MS)法检测钢渣中10种矿质元素。该方法的检出限为0.002～6.68μg.g-1,加标回收率为78.8%～105.7%,相对标准偏差(RSD)为0.68%～8.29%。该方法具有简便、快速、准确等特点,可用于钢渣中矿质元素的分析。
Established a variety of mineral slag detection methods. Slag samples were digested with HNO3-HF-HClO4 and 10 mineral elements in the slag were detected by inductively coupled plasma mass spectrometry (ICP-MS). The detection limit of this method was 0.002 ~ 6.68μg.g-1, the spiked recoveries ranged from 78.8% to 105.7%, and the relative standard deviations (RSDs) ranged from 0.68% to 8.29%. The method is simple, rapid and accurate and can be used for the analysis of mineral elements in steel slag.
