摘　　要：通过引用GB/T5009.11-2003《食品中总砷和无机砷的测定》中氢化物原子荧光光度法,进行了砷胆碱和砷甜菜碱两类有机砷回收率研究。结果表明:总砷单独加标的回收率符合GB/T5009.11-2003《食品中总砷和无机砷的测定方法》要求90-105%的范围,有机砷、有机砷和总砷的混合加标回收率均未达到方法GB/T5009.11-2003《食品中总砷和无机砷的测定方法》要求90-105%的范围,该方法对于砷胆碱和砷甜菜碱两类有机砷检测不灵敏。This paper through the use of GB/T5009.11-2003 the ＂determination of total arsenic and inorganic arsenic in food＂ by hydride generation atomic fluorescence spectrophotometry, the rate of arsenic choline and betaine two kinds of organic arsenic recovery. The results show that： the recovery rate of total arsenic spiked with GB/T5009.11-2003 method for＂ determination of total arsenic and inorganic arse- nic in food＂ 90-105%, organic arsenic, arsenic and arsenic mixed recoveries did not reach the GB/T5009.11-2003 method for ＂determina- tion of total arsenic and inorganic arsenic in food＂ range 90%-105% the method for arsenic, choline and betaine two kinds of organic arsenic detection sensitivity.
