    Abstract:
    A method for the simultaneous determination of trace arsenic and antimony in textile by intermittent flow-hydride generation-atomic fluorescence spectrometry with L-cysteine as a prereducer was developed. The optimal instrument condition was established. The influence factors such as the acidity of sample solution and carrier liquid, the concentrations of KBH4 and L-cysteine, the flow rate of carrier, and the interference of coexistent elements were investigated. The method was convenient and rapid. Under the optimal condition, the detection limits were 0.35 and 0.22 microg x L(-1), the relative standard deviations were 1.3% and 2.8%, and the recoveries were in the ranges of 93.6% - 98.4% and 92.2% - 103.6% for As and Sb respectively.
