| Abstract: | The effects of different pretreatment methods and test conditions on determination of polycyclic aromatic hydrocarbons(PAHs) in papermaking wastewater by GC-MS were investigated.It was found that the best extracting effects could be obtained by using DB-5 as the chromatographic column of GC-MS,methylene chloride as the extractant,30 min extraction time,0.1 g NaCl as salting-out agent,and 20 min mechanical oscillation.Using the optimized conditions the determination results showed that the 6 kinds of PHAs found in the influent leaved only 2 kinds in the effluent. |
