摘要：

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), HAuCl4, K2PdCl4, 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 10 nM5.0 mu M (R=0.998), and the detection limit is found to be 4.0 nM (S/N=3).
