摘　　要：以检测水果中有害元素(以As为例)含量为目的,实验选用赣南脐橙作为样品,采用湿法消解-原子荧光光谱法测定其果皮和果肉中有害元素砷的含量。实验先用湿法消解的方法预处理赣南脐橙的果皮和果肉,制备好样品,再用原子荧光光谱仪测定样品中痕量砷的含量。结果表明,脐橙果皮和果肉中含有微量砷元素,所检测的脐橙中平均含砷量为0.096 mg/kg(果皮)、0.020 mg/kg(果肉),脐橙样品中元素砷主要累积在果皮。With a view to detect the heavy metal element in fruits, the contents of element arsenic in peel and the fruit pulp of Southern Jiangxi navel orange were determined by wet digestion-atomic fluorescence spec- trometry. The fruit pulp and peel were preconditioned by wet digestion and then detected by atomic fluores- cence spectrometry. The results showed that trace arsenic was contained in pulp and peel, the average amount of arsenic per kg of Southern Jiangxi navel orange was 0.096 mg（peel） ,0. 020 （pulp） respectively, the total arsenic content in Southern Jiangxi navel orange conforms to China＇ s safety and health indicators. The element arsenic in Southern Jiangxi navel orange mainly rests in the peel.
