摘　　要：有机物料中砷含量的检测技术,采用快速微波酸消解前处理技术,原子荧光光谱仪定量。与国家标准检验方法GB/T 5009.11-2003《食品中总砷及无机砷的测定》比较,比国标前处理方法节省时间50%,试剂用量节省约50%。两种方法准确度未见显著性差异,精密度优于国家标准方法,适合对有机物料中砷进行快速测定。Arsenic content in organic materials was determined quantitatively by pretreatment of microwave digestion and atomic fluorescence spectrometer. Compared with the national standard method GB/T 5009.11- 2003 “Determination of total and inorganic arsenic in food”, The half time and reagent dosage were saved. The accuracy degree of the two methods had no significant difference, the precision degree of the new method was superior to the national standard method, so the new method adapted to rapid detection of arsenic in organic materials.
