Title:FPDAnalysisofSulfurCompoundsinGasoline
Abstract:
Sulfurcompoundsingasolinehavebeenofsignificantconcernduetotheirdetrimentaleffectsontheenvironment,humanhealth,andvehicleemissioncontrolsystems.ThispaperaimstoexploretheanalysisofsulfurcompoundsingasolineusingFlamePhotometricDetector(FPD)asaneffectivetoolforqualitativeandquantitativeanalysis.Thestudyhighlightstheimportanceofaccuratelydeterminingsulfurcontentingasolineanddiscussesthechallengesassociatedwithtraditionalanalysismethods.Furthermore,itdiscussestheprincipleandadvantagesofFPD,alongwithitsapplicationinsulfurcompoundanalysisingasoline.Overall,thispaperprovidesvaluableinsightsintoFPDanalysisofsulfurcompounds,emphasizingitspotentialtoenhancemonitoringandqualitycontrolmeasuresinthepetroleumindustry.
