食品中砷的原子荧光光度法测定研究进展

The Research Progress of Determination of Arsenic in Food by Atomic Fluorescence Spectrophotometry

砷是广泛分布于自然界的非金属元素,砷矿开采冶炼会引起土壤和水环境污染,食品加工过程中使用的某些化学添加剂也会导致食品中的砷污染。测定砷的常用国标法方法操作繁琐、灵敏度低。目前,研究较多的原子荧光光度法是一种高效率、低成本分析方法,具有灵敏度高、干扰少、线性范围宽和分析速度快的优点。对这种方法用于食品中砷的测定进行了综述。

As non-metallic elements, arsenic distributes in the world widely. Arsenic mining would cause soil and water pollution. Some chemical additives used in food processing including arsenic would pollute food. China Standard Method determine arsenic is with complex operation and low sensitivity. The atomic fluorescence spectrophotometry is a method with high efficiency and low cost, it has high sensitivity, less interference, wide linear range and fast analysis speed. Thus, the research progress of atomic fluorescence spectrophotometry is reviewed in this paper in order to provide a reference for related research.
