摘　　要：研究分析了饲料中总砷测定的不同前处理方法与检测方法对总砷测定结果的影响。结果表明,混合酸消解法对配合饲料、浓缩饲料、预混饲料中总砷的测定重复性好,精确度高;氢化物发生原子荧光光谱法测定饲料中总砷灵敏度高、回收率高、检测限低(3.6×10-11g/mL),同时具有污染小、操作简单便捷等优点。The different pretreatment methods and measure methods of total arsenic in feed were studied.The result showed that mixed acid digestion method had better reproducibility and accuracy when testing total arsenic in compoand feed,concentrated feed and premix digestion.Atomic fluorescence spectrometry of hydrid reaction method had high sensitivity,high reclaim ratio and low detection limit(3.6×10-11 g/mL) with advantages of lower pollution and simple operation.
