Abstract：After the sample was dissolved with nitric acid and hydrochloric acid(VHNO3∶VHCl=3∶2),sulfur in ferrovanadium was determined by inductively coupled plasma-atomic emission spectrometry with S 180.731 nm and S 182.034 nm as analytical line. Calibration curve was made by adding matrix solution in the standard solution to eliminate matrix interference. The results showed that when S 180.731 nm(185) was used as analytical line, the linear regression equation was I=3.033 9ρ+0.337 8 with linear correlation coefficient over 0.999 and detection limit of 0.009 4 μg/mL; when S 182.034 nm(184) was used as analytical line, the linear regression equation was I=2.586 3ρ—0.296 5 with linear correlation coefficient over 0.999 and detection limit of 0.020 μg/mL. Proposed method was applied to determination of sulfur in ferrovanadium certified reference material GSBH42004-92 and internal control sample ET-FT-04. The results were consistent with the certified values or those obtained by infrared method. The relative standard deviation (n=7) was 5.9 % and 2.7 %, respectively.
