Abstract:
Objective To establish a sensitive, reliable and simple method for determination of selenium(Se) in salt. Methods The salt samples were dissolved in water and added hydrochloric acid, thiourea, placed for 30 minutes under the room temperature, then used HG-AFS to determine Se. Results The linear range was 0.5-20 ?g/L, the detection limit was 0.06 ?g/L, RSD
