中文摘要:研究了在酸性介质中,苯胺抑制溴酸钾氧化荧光素的褪色反应,建立了抑制一褪色光度法测定痕量苯胺的新方法.方法的检出限为 4.2X10^(-8)gm·ml^(-1),测定范围为 2.25~20μg/25ml,方法简便灵敏,用于废水中苯胺的测定,结果满意.
外文摘要:It is reported that trace amounts of aniline can inhibit the decoloring reaction of fluorescein by potassium bromate in dilute sulfuric acid medium. The limit of detection is 4.2×10-8g · ml-1. The linear range is 2. 25-20μg/25ml. The proposed method has been applied to determination of aniline in waste water with satisfactory results.
