水中挥发酚检测方法初探

酚类属高毒物质,水中挥发酚的含量直接影响人类健康。近10年来,我国研究人员对水中挥发酚的测定方法开展了很多研究,特别对于采用4-氨基安替比林分光光度法(4-AAP)(GB 7490-1987)测定水中挥发酚的各个环节,如样品的采集、保存、预处理、试剂纯度、反应时间控制等相关因素进行了研究,找到了影响含量准确的因素,为测定水中挥发酚的含量提供了快速、准确、重复性好的方法。对一些非国标法测定水中挥发酚的方法也进行了介绍。文章对这些方法进行了分类总结。希望能对实验人员有所帮助。

An Approach to Determination Methods for Volatile Phenols

Volatile phenols are highly toxic substances.In the recent decade,Chinese researchers have studied a lot on the determination of volatile phenols in water,especially by the 4-aminoantipyrene(4-AAP) spectrophotometry,a national standard method(GB 7490-1987).Some influencing factors were categorised and summarised such as sample collection,preservation,pretreatment,reagent purity,reaction control,and etc. Some non-standard methods were herein classified and described as well.
