Summary

This laboratory study synthesised a novel hydrophobic ionic liquid ([DiOcAPmim][NTf2]) and evaluated its capacity to extract platinum group metals from simulated high-level nuclear liquid waste. The ionic liquid showed rapid extraction kinetics for palladium (equilibrium within 5 minutes at 2.05 M HNO₃) and demonstrated preferential selectivity for palladium over ruthenium and rhodium, with performance modulated by acid concentration and maintained across a range of co-existing metal ions.

UK applicability

This research is not directly applicable to UK farming systems, soil health, nutrient density, or human health. It addresses nuclear waste remediation chemistry and is outside the scope of Vitagri's Pulse Brain research interests.

Key measures

Extraction percentage of Pd(II), Ru(III), Rh(III); extraction kinetics (time to equilibrium); effect of nitric acid concentration (0.5–3+ M); effect of temperature; selectivity in presence of co-existing metal ions

Outcomes reported

The study measured extraction efficiency (percentage extraction) of palladium, ruthenium, and rhodium from simulated high-level nuclear liquid waste using a hydrophobic ionic liquid as a function of nitric acid concentration, contact time, temperature, and presence of co-existing metal ions. Results demonstrated preferential extraction of palladium over other platinum group metals across varying conditions.
