Electrochemical Detection of Pb and Cu by Using DTPA Functionalized Magnetic Nanoparticles

- Fe3O4MNPs were functionalized first with DA (Fe3O4/DA);
- Then further modified with DTPA (Fe3O4/DA/DTPA);
- Functionalization steps were tracked by spectroscopic and electrochemical methods;
- The CPE/Fe3O4/DA/DTPAelectrode was constructed fordetermination of Pb2+ and Cu2+.
