Synthesize Magnetic MnFe2O4 Nanoparticles

I need MnFe₂O₄ nanoparticles with demonstrably strong magnetic responsiveness, engineered specifically for magnetic separation in water-treatment systems that target heavy-metal ions such as lead and arsenic. The final material must be supplied as a dry, free-flowing powder so it can be redispersed or embedded into future treatment media without the complications of liquid carriers.

Because the application hinges on reliable magnetism and selectivity, I will require a concise characterization package confirming phase purity and magnetic performance. Typical data from XRD, TEM/SEM, and a VSM or comparable magnetometer will be sufficient; if you normally add ICP-OES or surface area details, please note that as well.

Deliverables
• Minimum 5 g of MnFe₂O₄ nanopowder produced under reproducible, lab-scale conditions
• Report (PDF) containing synthesis protocol, all characterization spectra/micrographs, and measured saturation magnetization

Please outline your proposed synthesis route, equipment, and estimated turnaround time in your bid.
