SKALAR连续流动分析仪测定地表水中的挥发酚 Title:DeterminationofVolatilePhenolsinSurfaceWaterUsingSKALARContinuousFlowAnalyzer Abstract: Surfacewatercontaminationbyvolatileorganiccompounds(VOCs),suchasvolatilephenols,posesasignificantthreattobothaquaticecosystemsandhumanhealth.ThispaperaimstodiscusstheuseoftheSKALARContinuousFlowAnalyzerforthedeterminationofvolatilephenolsinsurfacewater.TheSKALARanalyzeroffersareliableandautomatedmethodforthequantificationofthesecompounds,enablingeffectivemonitoringandassessmentofcontaminationlevelsinwaterbodies. Introduction: Volatilephenolsareorganiccompoundscommonlyfoundinindustrialeffluents,agriculturalrunoff,andurbanstormwater.Theyareknownfortheirpotentialtoxiceffectsonaquaticorganismsandcancauseadversehealtheffectsinhumanswhenconsumedviacontaminatedwatersources.Monitoringthepresenceofvolatilephenolsinsurfacewateristhereforecrucialformaintainingwaterqualitystandardsandensuringthesafetyofboththeenvironmentandhumanpopulations. AnalyticalMethodology: TheSKALARContinuousFlowAnalyzerisastate-of-the-artinstrumentthatoffersareliableandefficientmethodfortheanalysisofvolatilephenolsinwater.Theanalyzerisbasedonflowinjectionanalysis(FIA),whichallowsforautomatedandcontinuoussampleanalysis.Themethodologyinvolvesthefollowingsteps: 1.SamplePreparation:Surfacewatersamplesarecollectedandpretreatedtoremoveanyparticulatematterorinterference.Varioussamplepretreatmenttechniques,suchasfiltrationandsolid-phaseextraction,canbeemployeddependingonthespecificrequirementsofthestudy. 2.CalibrationCurve:Acalibrationcurveisconstructedusingstandardsolutionsofknownconcentrationsofvolatilephenols.TheSKALARanalyzeroffershighprecisionandaccuracyingeneratingthecalibrationcurve,ensuringreliablequantificationofthetargetanalytes. 3.ContinuousFlowAnalysis:Thepreparedsamples,alongwithreagentsandstandards,areinjectedintotheSKALARanalyzerthroughaflowcell.Theflowcellisequippedwithaspectrophotometricdetectorthatmeasurestheabsorbanceoftheanalytesataspecificwavelength.Theabsorbancevaluesarethe
