石油开采和冶金行业污水中矿物油的荧光和红外光谱法分析

表1石油开采和冶金行业污水中矿物油含量的红外光谱法测定结果污水来源总油类含量(mg/L)矿物油含量(mg/L)矿物油占总油比例(%)油田A55.030.755.8油田B47.933.469.7冶金A23.015.366.5冶金B47.826.755.94结论本文采用三维荧光光谱法分析了石油开采和冶金两个行业所排放的污水,提取了有代表性的4个企业污水的三维荧光指纹图和荧光特征峰,并结合红外光谱法分析比较了两个行业污水中的矿物油含量。结果表明石油开采行业污水中的矿物油含量高于冶金行业。研究结果证明了荧光光谱法可以在一定范围内应用于企业污水的矿物油测定,也为今后用荧光法准确定量测定污水中矿物油的含量打下了基础。参考文献[1]姜勇,赵萍,董铁有等.含油污泥油含量测定方法[J].环境科学与管理,2008,34(2):115—117.[2]郑健,周建光,陈焕文等.水体和土壤中矿物油的常用测量方法与仪器[J].分析仪器,2002,31(3):1—9.[3]中华人民共和国国家标准.水质石油类和动植物油的测定红外光度法[S].GB16488-1996.北京:中国标准出版社,2009.[4]马庆峰,王芳,张琳琳.一种新型油污染监测仪器[J].山东科学,2006,19(5):53—57.[5]许金钩,王尊本.荧光分析法[M].第3版.北京:科学出版社,2006.220—221.[6]中华人民共和国国家标准.水质采样的技术指导[S].GB12998-1991.北京:中国标准出版社,2009.[7]中华人民共和国国家标准.水质采样样品的保存和管理技术规定[S].GB12999-1991.北京:中国标准出版社,2009.FluorescenceandInfraredSpectroscopyAnalysisofMineralOilinWastewaterfromMiningandMetallurgyIndustriesYANGHai-Yaa,bWULiang-ZhuanaYUYuanaZHIJin-Fangaa(LaboratoryofPhoto-ElectricalFunctionalInterfaceMaterials,TechnicalInstituteofPhysicsandChemistry,ChineseAcademyofSciences,Beijing100190,P.R.China)b(GraduateUniversityofChineseAcademyofSciences,Beijing100049,P.R.China)AbstractThefluorescenceforthedeterminationofthecontentofmineraloilinwastewatersamplesthatwasobtainedfromfourtypicalfactoriesofminingindustriesandmetallurgyindustrieswasestablished,andthethreedimensionalfluorescencespectrumandfluorescencecharacteristicpeakofdischargedwastewaterwererespectivelyobtained,andthecongruentrelationshipofmineraloilcontentintwoindustrieswastewaterwithfluorescencespectradatawasanalyzed,andtheamountofmineraloilinwastewaterfromminingindustrieswashigherthanthatfrommetallurgyindustries.Thisresultwasevidencedbythecurrentnationalstandardmethodinfraredspectrophotometry.Thefluorescencemethodcanbetosomeextentappliedintodeterminationofmineraloilinwastewater.Theresultprovidesabasisfordevelopmentoffluorescencemethodfordetectionofmineraloilamount.KeywordsWastewater;MineralOil;Three-DimensionalFluorescenceSpectroscopy;InfraredSpectrometry2773第6期杨海涯等:石油开采和冶金行业污水中矿物油的荧光和红外光谱法分析
