- •
Non-stabilized iron oxide nanoparticles were synthesized from 12 to 20 nm in size.
- •
Effects of pH, time, and interfering ions were investigated for low level Cu2 + and Pb2 + removal.
- •
Pb2 + had higher binding capacity to the Fe3O4 nanomaterial.
- •
Cu2 + had higher binding capacity and Fe2O3 nanomaterial.
- •
Both Cu2 + and Pb2 + binding followed the Langmuir isotherm model.
