Pt/Pd-Fe<sub>3</sub>O<sub>4</sub> Nanoparticles for Removal of Humic Acids and Cr(VI)
Dumbbell-like Pt/Pd-Fe3O4 nanoparticles (NPs) for the effective and simultaneous removal of Humic Acids and Cr (VI) have been prepared by a one-step synthetic approach. The NPs after a ligand exchange process result suitable to be dispersed in water, electrochemical tests were carried out in a batch...

| description | Dumbbell-like Pt/Pd-Fe3O4 nanoparticles (NPs) for the effective and simultaneous removal of Humic Acids and Cr (VI) have been prepared by a one-step synthetic approach. The NPs after a ligand exchange process result suitable to be dispersed in water, electrochemical tests were carried out in a batch electrochemical cell. The NPs show excellent removal efficiency for total Cr. In particular ~ 64% of total Cr was removed in 30 min, while ~ 95 % of total Cr was removed in 9 h. Moreover, the complete removal of Cr (VI) was achieved in 1.5 h. Furthermore, they result able to remove ~ 95% of TOC after 9 h electrolysis, indicating a quite complete mineralization to CO2 of HAs. |
