| Abstract: | The micro selecnium in ostrich meat was determined by flame atomic absorption with cigarette tip additives as the microcolum adsorptive material and on line flow injection enrichment method.Under the optimal experimental conditions, the enrichment factor for selecnium is 4.7.The detection limit is 0.0017μg/mL,and the correlation coefficient is 0.9987.The method was applied in the detection of selenium in ostrich meat with RSD = 2.47% and additional average recovery of 99%-101%. |
