Determination of Manganese Content in Ferrotungsten by ICP-OES
The feasibility of using inductively coupled plasma optical emission spectrometry(ICP-OES)to determine man-ganese content in ferrotungsten was studied.Conditional experiments were conducted on the factors affecting elemental spec-tral lines,sample size,sample digestion,and spectral line interference.From the experimental results,it can be concluded that a series of working curves were prepared by selecting 257.611nm manganese element spectral lines,tungsten matrix,and high-purity iron as the base.ICP analysis of ferrotungsten standard substances was conducted,and the difference be-tween the analysis results and the standard values was within the allowable range.The relative standard deviation(RSD)of the 11 sets of data was less than 1.50%.
