| Abstract: | Objective:To establish a new method for determination of selenium in serum.Methods:The samples were diluted in a medium containing Triton X-100 before being introduced directly into the furnace and then detected by Zeeman GFAAS.Results:Under the best condition,the sensitivity and precision were suitable for the determination while the rate of recovery was controlled between 90% to 100%.The lowest detection limit of serum was 14.7 pg.Conclusion:This method is simple,quick,accurate and sensitive.It is a very good method for measuring selenium in serum. |
