文摘
- •
rGO-Ag nanocomposite was prepared using modified Tollens test.
- •
Reaction time dependent formation of Ag nanoparticles was analyzed.
- •
The nanocomposite was used for the electrochemical detection of 4-nitrophenol.
- •
The limit of detection was found to be 1.2 nM for 4-NP detection.
- •
It was applied for the determination of 4-NP in real water samples.
