GCMS分析碱法草浆造纸废水中的有机污染物组成

GC_MS孙剑辉,冯精兰,孙瑞霞(,,　453007)　:碱法草浆造纸废水在酸性条件下经乙醚萃取———K_D浓缩器浓缩,采用气相色谱_质谱(GC_MS)联用仪对其有机污染物进行了分析研究。结果表明,该废水中共含有29种有机物,其中主要为有机酸类,占有机物总量的50.84%。其次为难降解的呋喃类和毒性较大的苯环类有机物,它们分别占有机物总量的25.12%和13.53%。:碱法草浆造纸废水;有机污染物;GC_MS分析:X832　　　:A　　　:1002-6002(2005)01-0053-02AnalysisoforganicpollutantsinalkalistrawpulppapermakingwastewaterbyGC_MSSUNJian_hui,etal(CollegeofChemistryandEnvironmentalScience,HenanNormalUniversity,HenanKeyLaboratoryforEnvironmentalPollutionControl,Xinxiang453007,China)Abstract:Inthispaper,theextractionoforganiccompoundsinalkalistrawpulppapermakingwastewaterwithdiethyletherwasconductedinacidiccondition.ExtractedphaseafterconcentratedwithKuderna_Danish(K_D)concentratorwasanalyzedbyGC_MS.29kindsorganiccompoundswereidentified,anditwasfoundthatthemajororganiccompoundswereorganicacids,furansandbenzeneswithconcentrationsof50.84%,25.12%and13.53%,respectively.Keywords:alkalistrawpulppapermakingwastewater;organicpollutants;GC_MS:2003-10-22;:2004-06-20:(0323030400):(1957-),,,.　　,,80%,、。BOD5、COD。,,,。,,。,,。GC-MS、[1～3]。———K_D,_(GC_MS),。1　1.1　Agilent6890_5973GC_MS,Agilent7683。、,。40～80,300℃4h,。1.2　GC-MS:HP5(30m×0.25mmi.d.×0.25μm);N2,1mlmin;250℃,45℃,2min,10℃min250℃,2min,10℃min290℃,3min;0.2μl,35∶1;:15～500amu;EI,70eV,2400V,250℃。1.3　500ml,pH≤2,,　21　120052　　　　　EnvironmentalMonitoringinChinaVol.21　No.1Feb.2005　。200ml,25ml,5min,,,,,。,K_D1ml,GC_MS。2　GC_MS,(TIC)1,GC_MS,,、,1。1　1　(%)12.9070.3423.71921.7833.8132.7144.86920.1255.11917.5865.3480.3275.4463_0.5785.485_0.3095.5302_0.41106.0080.25116.2022_10.75127.3960.32137.5520.43147.980———0.39158.0911_0.68168.2633_0.64(%)178.3240.61188.8914_2.43199.1522.84209.2300.47219.6300.292210.4740.752311.1732.162411.6572.912513.0912,6_0.692615.4293__4_0.592715.9023__4_2.222816.5973.142916.6230.523017.7373__4_1.413118.412———1.38　54　　　　　　　　21　1　20052　:2003-12-13;:2004-06-20:(1952-),,,.　　1,29,、、、,50.84%。“”(POPs)[4],、、,20.12%、2.84%、2.16%,25.12%。,、、_、[5],2.71%、0.32%、0.30%、0.32%、9.88%,13.53%。,,。,。、。:[1],,.GCMS[J].,1996,12(5):30-32.[2],,.[J].()[J],2001,22(2):10-12.[3],,,.GCMS.[J],1994,15(3):36-41.[4],,.[J].,1990,6(4):1-3.[5],.[M].:,2002.5.a韩桂春1,谷　丰1,张忠臣2　(1.,　110031;2.,　)　:对分光光度法测定叶绿素a中样品研磨转移损失,离心后750nm处吸光值达不到0.005要求,加酸消除脱镁叶绿素,加酸量及加酸后测定时间等方面进行对比实验研究,提出了对分光光度法测定叶绿素a修改建议。:淡水;叶绿素a;测定方法:X832　　　:A　　　:1002-6002(2005)01-0055-03DiscussingaboutchlorophylladeterminationmethodinfreshwaterHANGui_chun1,etal(1.LiaoningProvinceEnvironmentalMonitoringCentre,Shenyang110031,China)Abstract:Whenchlorophyllaisdeterminedwithspectrophotometer,thesampledamnifyduringwhettingandtheabsorbencyat750nmdoesnotreach0.005aftercentrifugalmanagement,theletterpressmostlybringforwardthemodificationadviceondeterminingchlorophyllawithspectrophotometerbyaddingacidtoeliminatechlorophylladoffedmagnesiumandmakingcontradistinctiveexperimentsonaddingacidquantityanddeterminetimeafteraddingacidandsoon.Keywords:freshwater;chlorophylla;determinationmethod　　2001([2001]090)《()》,。a,,a,,。1　1.1　。1.2　1:《》()。　21　120052　　　　　EnvironmentalMonitoringinChinaVol.21　No.1Feb.2005
