文摘
- •
A modified electrode for heavy metal detection is constructed using electrochemically deposited graphene/bismuth composite.
- •
A stable graphene/bismuth nanocomposite film was formed on the electrode surface without any further treatment.
- •
Excellent stripping performance for trace zinc, cadmium and lead was obtained.
- •
The proposed electrochemical method was successfully applied to the analysis of trace metals in real samples.
