Introduction: Cyanideisahighlytoxiccompoundthatcancauseseverehealthissues,includingrespiratoryfailureandevendeath.Itcanenterthehumanbodythroughvarioussources,includingfoodandbeverages.Distilledspirits,suchaswhiskey,vodka,andrum,arepopularalcoholicbeveragesconsumedworldwide.However,thepresenceofcyanideindistilledspiritsposesapotentialhealthrisktoconsumers.Therefore,itisessentialtodevelopaccurateandefficientmethodsforcyanidedeterminationindistilledspirits.
