Title:AnalysisofIPBCAntifoulingAgentUsingHigh-PerformanceLiquidChromatographyandEvaluationofitsEfficacyinCombatingBiofouling
Abstract:
Biofouling,theunwantedaccumulationofmicroorganisms,plants,andanimalsonsurfacesimmersedinwater,canleadtoseriousdamageandeconomiclosses.Oneeffectivemethodtocombatbiofoulingistheuseofbiocidessuchas3-iodo-2-propynylbutylcarbamate(IPBC).Inthisstudy,wedevelopedahigh-performanceliquidchromatography(HPLC)methodfortheanalysisofIPBCinvariousmatrices.Furthermore,weevaluatedtheantifoulingefficacyofIPBCbydeterminingitsabilitytoinhibitthegrowthofbiofoulingorganismsinlaboratoryconditions.TheresultsshowedthatthedevelopedHPLCmethodwasreliableandsensitiveforthequantificationofIPBC.Moreover,IPBCexhibitedsignificantantifoulingactivityagainstarangeofbiofoulingorganisms,supportingitspotentialasaneffectivebiocideforbiofoulingcontrol.
