目的：建立少量酸微波消解‐原子荧光光谱仪同时测定禽蛋中砷、汞的方法。方法采用1 mL硝酸、对禽蛋样品用微波消解进行前处理，消解过的样品以硫脲‐抗坏血酸作为还原剂，无需赶酸，直接用原子荧光光谱仪测定禽蛋中砷、汞水平。结果该方法检出限：砷0．10μg／L、汞0．022μg／L。线性范围：砷0～30μg／L ，汞0～5．00μg／L ，相关系数均大于0．9996。样品加标回收率：砷92．1％～97．0％，汞92．5％～97．1％。结论该方法试剂用量少，简便快速。具有较高灵敏度、准确度、精密度，能够满足禽蛋样品中砷和汞同时测定的要求。

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 .
