| Abstract: | A method for determination of phosphorous, silicon and manganese in high carbon ferro chrome by inductively coupled plasma atomic emission spectrometry was studied. The sample was fused and dissolved with sodium peroxide in graphite crucible, acidified'by nitric acid and then directly analyzed by inductively coupled plasma atomic emission spectrometry. The detection ranges for phosphorous, silicon and manganese are 0. 005% ~0. 075%, 0. 30% ~6. 00% and 0. 03% ~2. 00%, respectively. The relative standard deviation of this method is less than 6%. The recommended method not only proved to be simple and rapid but showed satisfying accuracy as well. |
