摘要：
The novel reduced graphene oxide-bismuth (RGO-Bi) nanocomposites were successfully synthesized through one-step electrochemical reduced deposition and used to modify disposable screen-printed electrode (SPE) for determination of Pb(II). By electrochemical deposition, a large number of Bi particles were distributed on RGO. Combined the unique structure and electronic properties of RGO with the ability of Bi to form alloys with other metals, the RGO-Bi/SPE has shown wide linear range and low detection limit for determination of Pb(II). Additionally, the RGO-Bi/SPE was successfully applied to the rapid determination of Pb(II) in real coastal sediment pore waters. (C) 2015 The Electrochemical Society. All rights reserved.
