| Abstract: | In this paper,the arsenic and stibium in steel were determined by FI-HG-AAS. The operating conditions such as apparatus,reducing agent,acidity,concentration of KBH4,the influence of coexistent ion were optimalized. Linear relationship was obtained in the range of 0.05 to 100μg/L for arsenic with the linear regression equation of CAs= 0. 047A--0. 003,correlation coefficient of 0. 9996, detection limit of 0. 03μg·L^-1 ;and RSD of 1.12% for arsenic. The Linear relationship in the range of 0. 05 to 100μg/L for stibium with the linear regression equation of CSb = 0. 0094A--0. 0003, correlation coefficient of 0. 9996,detection limit of 0.03μg·L^-1 ,and RSD of 1.06% for stibium. This method is sensitive, accurate and credible, convenient, fast, and can meet the needs of the determination of Arsenic and stibium in steel. |
