Determination of Co, Cr, Cu, Mo, Ni, Pb, Sn, W, Y and Zn in Molybdenum Ores by Inductively Coupled Plasma-Atomic Emission Specrometry

The quantitative analysis of 10 elements including Co, Cr, Cu, Mo, Ni, Pb, Sn, W, Y and Zn in molybdenum ores by inductively coupled plasmaatomic emission spectrometry (ICP-AES) with mixed acid sample pretreatment was performed. The sample pretreatment parameters and instrument operation condition were optimized. The method has been verified by determination of these components in molybdenum ore National Standard Reference Materials and the results are in agreement with certified values with precision of less than 3.0%RSD
