| Abstract: | A rapid hydride generation atomic fluorescence spectrometry was developed to determination of arsenic in edible oil.Samples were treated by digestion-petroleum ether extraction.The pretreatment method,the liner range of determination and limit of detection of the method were also investigated.The relative standard deviation is less than 1.79%.The recovers are in the range of 96.7%- 103.8%. |
