Rice University Researchers Achieve 195 mg/g Dysprosium Capture With Engineered Rare Earth Recovery Material

Highlights

• Modified MIL-101 framework with PMIDA molecules captured up to 195 mg/g dysprosium, 175 mg/g gadolinium, and 160 mg/g neodymium in lab tests.
• Iron at 100 times the rare earth concentration caused minimal interference, suggesting selectivity potential in complex wastewater streams.
• Repeated use reduced adsorption capacity, and commercial viability including separation, purification, and operating costs remains unproven.
