化纤厂棉浆粕废水中有机污染物的GCMS分析孙瑞霞

-PTCA(PARTB:CHEM.ANAL.)2006426GC-MS1,2,1＊,1(1.,,453007;2.,454003)　:化纤厂棉浆粕废水在酸性条件下经乙醚萃取———Kuderna-Danish(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,在该废水中检测出14种有机物,主要污染物为有机酸类,占有机物总量的35.19%。其次为酯类和酮类,分别占有机物总量的30.03%和19.68%。此外,浆粕废水中还检测出二苯胺和环境优先污染物苯酚,分别占有机物总量的7.85%和5.42%。:棉浆粕废水;有机污染物;GC/MS分析:O657.37　　　:A　　　:1001-4020(2006)06-0457-02GC-MSANALYSISOFORGANICPOLLUTANTSINCOTTONPULPWASTEWATERFROMFIBERFACTORYSUNRui-xia1,SUYong-xiang2,SUNJian-hui1＊,FENGJing-lan1(1.CollegeofChemistryandEnvironmentalSciences,HenanNormalUniversity,HenanKeyLaboratoryforEnvironmentalPollutionControl,Xinxiang453007,China;2.DepatmentofBiochemistryandEnvironmentalEngineering,JiaozuoUniversity,Jiaozuo454003,China)Abstract:TheorganicpollutantsincottonpulpwastewaterwereextractedwithdimethyletherunderacidicconditionsandconcentratedusingaKuderna-Danishconcentrator.GC-MSwasusedfortheanalysisofpollutantsintheconcentrate.14organicmatterswereidentified,includingthemajorcompoundsorganicacids,estersandketoneswithconcentrationof35.19%,30.03%and19.68%respectively.Inaddition,diphenylamineandphenolasprioritypollutantwerealsoidentifiedamountedto7.85%and5.42%respectively,ofthetotalorganicpollutants.Keywords:Cottonpulpwastewater;Organicpollutants;GC-MS　　,、、,、、、。,、、。、、、、pH11、。:2005-01-10:(0323030400)。:(1957-),,,,　。＊,,80%,、。BOD5、COD。,,,。,,。,,。·457·-:GC-MSGC/MS、[1～3]。———K-D,-(GC-MS),。1　1.1　Agilent6890-5973GC-MS,Agilent7683。。425mm～180μm(40～80),300℃4h,。1.2　GC/MSHP5(30m×0.25mmi.d.,0.25μm);N2,1mL·min-1;250℃,45℃,2min,10℃·min-1250℃,2min,10℃·min-1290℃,3min;0.2μL,35∶1;15～500amu;EI,70eV,2400V,250℃。2　2.1　,pHCOD112144mg·L-1。:()200mL,pH≤2,10mL3,,,K-D1mL,GC-MS[4]。2.2　GC-MS,GC-MS,,,1。1,14。,35.19%。,30.03%、19.68%。,[5],1　GC/MSTab.1　OrganicpollutantsincottonpulpwastewaterextractedwithetheranddeterminedbyGC/MSPeak#Retentiontime(t/min)Organicpollutant(%)Relativepercentage14.336.7125.243-7.5935.442-4.7347.375.4258.172--3--2-2.2268.653,4--2--2-1.5879.693--2--2-6.45810.063,3--2--1.82910.126--4--1,2-4.921011.433,5--2--2-4.511111.7016.161216.527.851325.95-2-13.591427.881.831528.41-2-14.627.85%5.42%。,,。,。、。:[1]　,,.GC/MS[J].,1996,12(5):30～32.[2]　,,.[J].(),2001,22(2):10～12.[3]　,,,.GC/MS[J].,1994,15(3):36～41.[4]　,.[J].,1996,12(5):18～21.[5]　,,.[M].:,1995.4.·458·
