Abstract:After the sample was dissolved with nitric acid and hydrochloric acid(VHNO3∶VHCl=3∶2),sulfur in ferrovanadium was determined by inductively coupled plasmaatomic 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 GSBH4200492 and internal control sample ETFT04. 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.
