| Abstract: | A method for determination of binding selenium in human red erythrocyte membrane with Ni and Mg (NO_3)_2 as matrix modifier in graphite furnace AAS is described. Under the optimum condition,the characteristic mass m is 16. 0pg/0. 0044A. S,the detection limit is 7.4pg,the recovery is 92%-108 % ,the ralative standard deviation is less than 8. 9%.10 elements do not interfere with the determination of Se. The method had been used to analyse practical samples ,satisfactory results are obtained. It is simple and rapid. |
