Sulfur‐Limonene Polysulfide: A Material Synthesized Entirely from Industrial By‐Products and Its Use in Removing Toxic Metals from Water and Soil


A polysulfide material was synthesized by the direct reaction of sulfur and D‐limonene, by‐products of the petroleum and citrus industries, respectively. The resulting material was processed into functional coatings or molded into solid devices for the removal of palladium and mercury salts from water and soil. The binding of mercury(II) to the sulfur‐limonene polysulfide resulted in a color change. These properties motivate application in next‐generation environmental remediation and mercury sensing.

Aus den industriellen Koppelprodukten Schwefel und Limonen wurde ein Polysulfid synthetisiert, das zu Beschichtungen weiterverarbeitet oder in Form gebracht werden kann. Das Material erkennt selektiv Quecksilber(II), das es unter Bildung einer hellgelben Ablagerung bindet (siehe Bild). Anwendungen des Polysulfids in der Wasser‐ und Bodenreinigung werden vorgestellt.

    Spectroscopically Controlled Quantum Bits

    Molecules could make useful systems for quantum computers, but they must contain individually addressable, interacting quantum bit centers. In the journal Angewandte Chemie, a team of researchers has now presented a molecular model with three different, coupled qubit centers. As each center ... more

    Fuel from a Greenhouse Gas

    One step toward carbon dioxide (CO2) neutrality and the mitigation of both the greenhouse effect and the energy crisis would be to convert CO2 into hydrocarbon-based fuels like methane using light. In the journal Angewandte Chemie, a Chinese research team has introduced a highly effective p ... more

    Economical PEF Production

    One possible replacement for drink containers made from PET is polyethylene furandicarboxylate (PEF), made from renewable resources. However, the production of the raw material for PEF from biomass is still rather inefficient. A new titanium-based photocatalyst could be about to change this ... more
