Recovery of Noble Metals (Au, Pt, Ir, and Ta) from Spent Single-Use Medical–Technological Products

Minerals, Год журнала: 2024, Номер 14(1), С. 90 - 90

Due to their unique properties, i.e., fluoroscopy response and inertness, noble metals alloys are present in several widespread medical–technological products, such as catheters, guide-wires, stents. Despite value, these products serve single-use consumables, following a fate of solid waste disposal loss valuable metals. This work studies the development treatment methodology recover Pt, Ir, Au, Ta from certain commercial commonly used for medical practices. In particular, sequence preliminary pyrolysis, aiming at polymer elimination, well an acid digestion step selective dissolution, is suggested. Pyrolysis was capable enriching samples with targeted metals, though small change oxidation states observed. Still, fully able successfully separate Au using 50% v/v aqua regia solution 30 min room temperature Pt/Ir concentrated 72 h under heating. Dissolution required different leaching solution, HF/H2SO4 mixture 10 According developed method, extraction slurry provides high potential complete recovery valorization otherwise disposed wastes.
