| Abstract: | In this paper,a method for determining of beryllium in rice ad flour by platform graphite furnace atomic absorption spectrometry using a slurry technique is described.A self made graphite platform was installed in pyrolytic graphite tube of graphite furnace.Under the established optimum experimental condition the calibration graphic linear for 0-10ng/mL of beryllium.Sensitivities is 1.9 pg/0.0044A .The method was successfully applied to the determination rice and flour samples with recoveries between 96.0%-100.0%,detection limit of 1.4pg(3SD)and the RSD 2.9%-5.0%. |
