This approach captures gadolinium in urine post magnetic resonance imaging, suggesting better environmental sustainability and recycling.

To evaluate methods for preventing gadolinium from contaminating surface water after its use in medical imaging.
Described the use of solid-phase adsorbents
Assessed commercially available adsorbents for capturing gadolinium
Evaluated effectiveness of adsorbents at concentrations found in urine
Less than 25% of gadolinium is removed from treated effluent in wastewater treatment
Solid-phase adsorbents successfully captured gadolinium-containing contrast agents
Provides an environmentally friendly solution compared to current practices of disposal

Wijesinghe et al. (2026) studied this question.
