砷是一种污染元素,正常食品中都含有极微量的砷。因此,砷是食品卫生理化检验的一个重要指标。目前,国家标准方法[1]中样品有两种前处理方法:灰化法消化和湿法消化,前处理较烦琐。湿法消化中的酸雾对人体有害[2];灰化法消化不完全时,影响结果的准确性[2]。本文对样品中砷测定的 Arsenic is a contaminating element that contains trace amounts of arsenic in normal foods. Therefore, arsenic is an important indicator of physical and chemical testing of food hygiene. At present, there are two pretreatment methods for the samples in the national standard method [1]: ashing and wet digestion, pretreatment is more cumbersome. Acid digestion in wet digestion is harmful to the human body [2]; when the ashing method is incompletely digested, the accuracy of the result is affected [2]. In this paper, the determination of arsenic in the sample
