五氯苯酚(PCP)在环境中的存在和归宿已引起环境科学家的重视,对PCP的测定,文献报道用GC法测定PCP不仅回收率低,而且需要柱前衍生反应,且衍生物毒性大。目前美国国家环境保护局已将GC法测定PCP列入摒弃方法之列;用4-氨替氨基比林(4-AAP)方法测定PCP,不仅费时,而且测出的只是总酚的含量,在其它酚存在下不能单独测出PCP含量,因而限制了AAP法的应用。 本文以HPLC-UV法测定井水、雨水中PCP含量,前处理较简单,不需要特殊试剂,方法的灵敏度较高,重现性良好。
The existence and fate of pentachlorophenol (PCP) in the environment have attracted the attention of environmental scientists. For the determination of PCP, it has been reported in the literature that the determination of PCP by GC method not only has a low recovery rate but also requires pre-column derivatization with high derivatives toxicity. At present, the United States Environmental Protection Agency has been included in the determination of PCP by GC method to exclude the column; with 4-amino-aminopyrine (4-AAP) method for the determination of PCP, not only time-consuming, and measured only the total phenolic content, The presence of other phenols can not be measured separately PCP content, thus limiting the AAP method. In this paper, the HPLC-UV method for the determination of PCP in well water and rainwater is simpler, without special reagents. The method has high sensitivity and good reproducibility.
