文摘
- •
Oxidized carbon dots were obtained from cellulose fibers.
- •
The carbon dots (CD) exhibited large amounts of acid functional groups (AFG).
- •
The AFG were characterized by fit data of potentiometric titration curves.
- •
The methodology used showed a good reproducibility and stability.
- •
A simple, fast and powerful tool to characterize the acid–base properties of CD.
