摘要
提出一种流动注射 -氢化物发生双道原子荧光同时测定水样中痕量砷和锑的新方法。砷和锑的标准曲线范围为 0～ 40μg· L-1,相对标准偏差小于 5% ,回收率为 90 %～ 1 0 7% ,检出限为0 .0 2 5μg·L-1。
In this paper, a new method for the simultaneous determination of microamounts of arsenic and antimony in water sample by flow injection hydride generation double channel atomic fluorescence spectrometry is proposed. A linear relationship between the signal measured and the concentrations of both As (Ⅲ) and Sb(Ⅲ) is found to be 0~40μg·L -1 . The RSD′s found are less than 5%, and the recoveries found are between 92%~107%. A limit of detection of 0.025μg·L -1 is obtained.
