摘要
采用气相色谱和氮磷检测器分析工业废水中的苯胺,调节工业废水p H使得废水中苯胺变成胺盐,通过液液萃取除杂。线性范围0-100.0μg/L,方法检出限1.0μg/L。平均回收率在67.2%-89.5%之间,相对标准偏差RSD〈10%。
The method of benzenamine in waste water by gas phase chromatography with nitrogen phosphorus detector analysis was developed. The waste water sample pH was regulated, the aniline was transformed into amine salt and was purified by liquid-liquid extraction. The linear range was 0-80 μg/L and the detection limit of 1.0 μg/L. The average recoveries of aniline were 67.2 %-89.5 % and RSD were less than 10 % respectively.
