Abstract:
Objective To establish a sensitive ,reliable and convenient method for determination of total selenium(Se) in salt by HG-AFS. Methods The salt samples were dissolved and added hydrochloric acid (HCl),after heating by boiling water ,used HG-AFS to determinate Se. Results The linear range of the method was 0.5-400 ?g/L, The correlation coefficient was larger than 0.999 5, the recovery rates were 95.7%-102.8%. If 1 ml sample was collected, the detection limit was 0.08 ?g/L. Conclusion The method is sensitive, reliable, simple, less sample usage, and is an ideal method for determination of total selenium in salt.
