摘要
本文深入研究了工业废水中ＰＡＨ的前处理及液相色谱分析方法．建立了工业废水在酸性条件下，用二氯甲烷萃取ＰＡＨ的简单前处理方法和采用ＺＯＲＢＡＸＣ８柱与ＲＦ－５１０萤光检测器串联测定７种ＰＡＨ，用ＳＰＤ－２ＡＳ紫外检测器测定３种ＰＡＨ的液相色谱法．该方法准确度大于９０％，精密度小于５％，各种ＰＡＨ的检测下限为１．０００－０．００３ｎｇ．
This article studies the pretreatment of PAH in industrial wastewater and analysis meth ods of liqid chromatography.under the acid condition,it's found a kind of simple pretre atment method of PAH and using ZORBAX C8 column and R10 fluorescent light examiner to determine 7 kinds of PAH.and using SPD 2AS ultraviolet examiner to determine 3 kinds of PAH.The accuracy is more than 90% and the precision is less than 5%.The lower limit value of exami naion of various PAH are from 1. 000- 0. 003ng.
