Electrochemical studies on the interfacial behaviors for the eco-friendly magnetic nanoparticles based on γ-Fe2O3

- The interfacial properties were studied by three different electrochemical methods.
- The grafted gallic acid induced the enhanced chelating ability.
- Cu anodic stripping behavior depended on the coordination environment
- “Prussian blue” analogues deposited on Cu2+-chelated electrode during EIS measurements.
