A polymer made from sulfur and limonene was used to coat silica gel and then evaluated as a mercury sorbent. A kinetic model of mercury uptake was established for a range of pH values and concentrations of sodium chloride. Mercury uptake was generally rapid from pH = 3 to pH = 11.

The resulting material exhibited improved uptake of mercury from water compared to the polymer. The carbonisation could also be done after using the polymer to clean up oil spills, which suprisingly improved mercury uptake to levels rivaling commercial carbons.

- Inverse vulcanization produces innovative materials from sulfur and unsaturated cross-linkers, which are useful in areas like energy storage and environmental remediation.
- Despite their advantages, there's a challenge in recycling and reprocessing these polymers.
- This study introduces a method called reactive compression molding that allows these sulfur-based polymers to be reshaped and chemically bonded at low temperatures, enabling repair and repurposing into new materials.
