摘　　要：建立采用王水溶样,酒石酸溶液络合锑,在盐酸介质下,用火焰原子吸收光谱法测定精锑中微量铋;并对共存元素干扰、仪器分析参数等因素进行了研究,确定了最佳分析条件。结果表明:该方法测定结果的准确度和精密度均满足需要、操作简便。Through dissolution of sample in aqua regia and complexation of tartaric acid solution and antimony, trace bismuth in refined antimony was determined by flame atomie absorption spectrometry in hydroehlorie acid medium. An investigation was made on the interferenee of eoexisting elements and the analytic parameters of the apparatus and other factors. The optimum analysis conditions were determined. The results show that the measurement aceuraey and precision of this method can meet the need, besides its simple operation.
