摘要：

We successfully developed a GH-PP-Pt/GCE electrode by compounding graphene hydrogel (GH) with poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS), and in situ electrodeposition of Pt nanoparticles. The experimental results prove that the performance of GH-PP-Pt/GCE to trace copper ions significantly improved, the sensitivity reaches 45.673 mu A/mu mol L-1, the limit of detection is as low as 9.9 nmol L-1, and the linear range is 0.08-10 mu mol L-1. Its detection ability is at a relatively high level among the existing Cu2+ electrochemical detection sensors, and the repeatability, stability, and anti-interference are good.
