摘要
研究了仪器最佳工作条件 ,介质及共存离子干扰试验和样品处理方法。该方法样品采用湿法消化 ,以浓硫酸和过氧化氢使聚酯炭化 ,将有机物质氧化成无机的试液进行测定。用消化罩控制过氧化氢流速 ,不仅节省劳力而且提高工效及分析准确度。回收率为 96.5%~ 1 0 1 %
The optimum working conditions of the instrument, the interference of the medium and coexisting ions and the sample treatment method have been studied in this article. The sample of polyester fiber was treated with wet digestion method and carbnized by concentrated sulfuric acid and hydrogen peroxide. The organism of the sample was oxidized and preoxide into inorganic solution in which the antimong content was determined precisely.
