Abstract:A method for the determination of Co,Cu,Fe,Mg,Mn,W,Zr in molybdenum by ICP-OES was established. The sample dissolution method and the analytical spectral lines were determined. The matrix matching was used to eliminate the effects of the base of molybdenum on these elements. The relative standard deviations (RSDs) for the determination of each element were all less than 3% and the recovery coefficient was between 80.95% and 110.4%. The experiments showed that this method is rapid, accurate and applicable to multi-element simultaneous determination in molybdenum.
