| Abstract: | A method for determination of Ca, Mg, Cr, Co, Mn, Zn and Ti in magneticpowder with a sequential ICP spectrometer has been developed. The sample wasdecomposed with mixed sulfuric, phosphoric and nitric acids. Solutions containing purematrix element and the sample were used to investigate spectral interference with thesystem's "Acquire Scan Data" software. For several trace elements interference cor-rection was indispensable. The average recovery of the method for seven elements isbetween 90% and 104%. |
