[Determination of Se in serum by ICP-AES].

The serum sample solution was prepared by using acid digestion and the Se concentration in it was determined by ICP-AES. At the same time, the interference from Fe and the interference-free method were studied. The results showed that the recovery of standard addition was 91.6%, the relative standard deviation(n = 10) was 2.147% and when KOH was added to the sample solution the interference was reduced greatly. The method is efficient, accurate and easy to operate.
