| Abstract: | 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. |
