纳米材料的土柱淋溶行为及其对铜和菲的吸附和协同 运移研究的开题报告 Title:InvestigationoftheLeachingBehaviorofNano MaterialsinSoilColumnsandTheirAdsorptionandSynergistic TransportofCopperandPhenanthrene 1.Background Contaminationofsoilandgroundwaterwithheavymetals andorganicpollutantsisamajorenvironmentalissue. Nanomaterialshaveshowngreatpotentialinremediationofsoil andwaterduetotheiruniquephysico-chemicalproperties. However,itisnecessarytounderstandtheirtransportandfatein theenvironmentbeforetheirlarge-scaleapplication.Theobjective ofthisresearchistoinvestigatetheleachingbehaviorof nanomaterialsinsoilcolumnsandtheirinteractionswithcopper andphenanthrene. 2.ResearchQuestions -Whatistheleachingbehaviorofdifferenttypesof nanomaterialsinsoilcolumns? -Howdocopperandphenanthreneadsorbtothe nanomaterialsinsoilcolumns? -Howdocopperandphenanthreneaffectthetransportof nanomaterialsinsoilcolumns? -Whatisthesynergisticeffectofcopperandphenanthrene ontheadsorptionandtransportofnanomaterialsinsoilcolumns? 3.Methodology -Preparationofnanomaterials:Differenttypesof nanomaterials,suchascarbonnanotubes,grapheneoxideand ironoxidenanoparticles,willbesynthesizedandcharacterized. -Soilcolumnexperiments:Soilcolumnswillbepackedwitha mixtureofsandandsoil,anddifferenttypesofnanomaterialswill beintroducedatthetop.Subsequently,asolutioncontaining copperandphenanthrenewillbeintroducedtosimulatethe contaminatedgroundwater.Sampleswillbecollectedatdifferent
