Abstract：

In　this　study,　a　3Au-1Pd　alloy　nanoparticles/graphene　composite　(3Au-1Pd　alloy　NPs/GN)　with　carboxyl　groups　and　hydroxyl　groups　was　prepared　facilely　by　co-reduction　of　graphene　oxide　(GO),　HAuCl　4,　K　2PdCl　4,　with　an　Au-Pd　alloy　molar　ratio　of　3:1.　The　composite　modified　glass　carbon　electrode　(GCE)　showed　a　good　performance　for　detecting　bisphenol　A　(BPA)　due　to　the　enhanced　electron　transfer　kinetics　and　large　active　surface　area.　The　effective　enrichment　of　BPA　is　attributed　to　the　carboxyl　groups　and　hydroxyl　groups　on　the　composite.　According　to　the　results　of　differential　pulse　voltammetry　(DPV),　the　BPA　oxidation　current　is　linear　to　its　concentration　in　the　range　of　10nM-5.0μM　(R=0.998),　and　the　detection　limit　is　found　to　be　4.0nM　(S/N=3).　©　2012　WILEY-VCH　Verlag　GmbH　&　Co.　KGaA,　Weinheim.
