Abstract:
？Asimpleandsensitiveelectrochemicaldetectionofcaffeine(CAF)usingasingle-walledcarbonnanotubesoncarbon-ceramicelectrode(SWCNT/CCE)isreported.CAFwasoxidizedatthesurfaceofthemodifiedelectrodetoproduceananodicpeakat1.38Vversusthesaturatedcalomelelectrodein0.01mol/L,pH1.7H2SO4solutionincyclicvoltammetry.Theexperimentalparameters,namely,typeofelectrolyte,pHvalue,andamountofSWCNTscasted,wereoptimized.Usingtheoptimumconditions,theanodicpeakcurrentindifferentialpulsevoltammetrywaslinearwithCAFconcentrationintherangeof2.5×10-7-1.0×10-4mol/L.Thedetectionlimitwas1.2×10-7mol/L(S/N=3).Themodifiedelectrodeexhibitedgoodstabilityandcanbeeasilyregenerated.Therelativestandarddeviationofthepeakcurrentobtainedfora5.0×10-5mol/LCAFsolutionwas3.0%.Theinfluenceofsomeimportantbiologicalcompounds,namely,ascorbicacid,dopamine,anduricacidandaddictivecompoundslikecodeine,morphine,andacetaminophenontheCAFanodicpeakcurrentwasexamined.ThemethodwassuccessfullyappliedforthedeterminationofCAFinsomepracticalsamples.
