Abstract:
Objective To establish a small amount of acid ,microwave digestion‐atomic fluorescence spectrometer method was developed for the determination of arsenic and mercury in eggs at the same time .Methods The sample was digested with 1 ml HNO3 ,After digestion ,the sample was deoxidized with sulfocarbamide and vitamin C and then determined by AFs without dispel‐ling the acid .Results The sample was digested with 1 mL HNO3 ,After digestion ,the sample was deoxidized with sulfocarbamide and vitamin C and then determined by AFs without dispelling the acid .Conclusion The method is simple ,rapid and with little pol‐lution .The determination of arsenic and mercury in eggs by Atomic Fluorescence Spectrometry using microwave digestion were de‐veloped with satisfactory sensitivity ,accurate and precision .
