Title:MicrowaveWeightLossMethodforDeterminationofPotassiumOxideinPotassiumSulfateandPotassiumChloride
Abstract:
Potassiumcompounds,suchaspotassiumsulfatesandpotassiumchlorides,arewidelyusedinvariousindustries.Theaccuratedeterminationofpotassiumoxide(K2O)contentinthesecompoundsiscrucialforqualitycontrol.Inthisstudy,weinvestigatetheapplicationofthetetraphenylboronpotassium(KTPB)methodcombinedwithmicrowavetreatmentforthedeterminationofK2Oinpotassiumsulfatesandpotassiumchlorides.Theprincipleofthemethod,experimentalprocedures,andanalyticalresultsarepresented.TheobtainedresultsdemonstratethepotentialofthismethodasareliableandefficienttechniqueforthedeterminationofK2Ocontentinpotassiumcompounds.
1.Introduction:
Potassiumcompounds,particularlypotassiumsulfatesandpotassiumchlorides,havevariousapplications,includingfertilizers,pharmaceuticals,glassmanufacturing,andchemicalsynthesis.TheaccuratedeterminationofK2Ocontentinthesecompoundsisessentialforqualitycontrolandcompliancewithindustrystandards.SeveralanalyticaltechniqueshavebeendevelopedforK2Odetermination,includingacid-basetitration,flamephotometry,andspectroscopicmethods.However,thesemethodsoftensufferfrominherentlimitations,suchastime-consumingsampleprocessing,theneedforextensiveinstrumentation,andinterferencesfromotheranalytes.Therefore,thedevelopmentofasimple,rapid,andaccuratemethodforK2Odeterminationinpotassiumcompoundsishighlydesirable.
2.Methodology:
Theproposedmethodutilizestheclassictetraphenylboronpotassium(KTPB)gravimetricmethod,combinedwithmicrowavetreatment,forthedeterminationofK2Ocontent.TheKTPBmethodisbasedontheprecipitationreactionbetweenK+ionsandtetraphenylboronanions(TPB-)toforminsolubleKTPB.Theresultingprecipitateiscollected,washed,anddried,followedbyweighingtodeterminetheK2Ocontent.
