FeS在有机络合铜锡废水处理中的应用研究的开题报告Title:ApplicationresearchofFeSinorganiccomplexationcopper-tinwastewatertreatmentAbstract:Withtherapiddevelopmentofindustry,thedischargeofindustrialwastewaterhasbecomeaseriousenvironmentalproblem.Theorganiccomplexationcopper-tinwastewaterisoneofthetypicalindustrialwastewaterwithhighcomplexityandtoxicity.Inthisstudy,FeSwasselectedastheadsorbentmaterialforthetreatmentoforganiccomplexationcopper-tinwastewater.ThebasiccharacteristicsofFeSwerestudied,includingthemorphology,crystalstructure,surfacearea,andfunctionalgroups.TheeffectsofFeSdosage,initialpH,contacttime,andinitialconcentrationofCuandSnontheadsorptionperformancewereinvestigated.Furthermore,themechanismofremovalwasexploredbyanalyzingthesurfaceproperties,FTIRspectra,andXPSspectraofFeSbeforeandafteradsorption.Thefeasibilityandefficiencyoftheproposedmethodwereevaluatedintheexperiments.TheresultsshowedthattheFeShadahighremovalefficiencyforbothCuandSn,andtheoptimalconditionswereobtainedasfollows:FeSdosage1.5g/L,initialpH7.0,contacttime90min,initialCuandSnconcentrationof80mg/L,and90%and83%ofCuandSnwereremoved,respectively.Themechanismofremovalwasmainlyduetothesurfacecomplexationandprecipitation.Theproposedmethodprovidedasimpleandeffectivesolutionforthetreatmentoforganiccomplexationcopper-tinwastewater.Keywords:FeS;organiccomplexationcopper-tinwastewater;adsorption;mechanism.
